HMC984LP4E is a high-performance, ultra-low phase noise, SiGe BiCMOS Phase-Frequency Detector and Charge Pump targeted to be used together with the HMC983LP5E (Fractional Frequency Divider) to together form a high performance, low noise, ultra low spurious emission fractional-N frequency synthesizer.Although best performance and maximum features are achieved when used together with the HMC983LP5E, the HMC984LP4E can also be used as a stand-alone, low phase noise phase frequency detector.The HMC984LP4E can receive differential VCO input, and a reference frequency as high as 150 MHz. It features a 14-bit reference frequency R-Divider, and automatic and/or configurable Lock Detect Indicator, as well as integrated CSP (Cycle Slip Prevention) capability, when used together with the HMC983LP5E, that significantly improves frequency lock time.Integrated Charge Pump phase swap option enables seamless interfaced to VCOs and active loop filters with inverted polarity.Additional features include adjustable Charge Pump gain and offset current that improve linearity and performance, and a Soft Reset feature that resets all register to default values without having to perform a power-cycle.The HMC984LP4E is housed in a compact 24 pin 4×4 mm LP4 package.

The HMC1087 is an 8W Gallium Nitride (GaN) MMIC Power Amplifier which operates between 2 and 20 GHz. The amplifier typically provides 11dB of small signal gain, +39 dBm of saturated output power, and +45 dBm output IP3 at +29 dBm output power per tone. The HMC1087 draws 850 mA quiescent current from a +28V DC supply. The RF I/Os are matched to 50 Ohms for ease of integration into Multi-Chip-Modules (MCMs). All electrical performance data was aquired with the die eutectically attached to 1.02 mm (40 mil) thick CuMo carrier with multiple 1.0 mil diameter ball bonds connecting the die to 50 Ohm transmission lines on alumina.Applications Test Instrumentation General Communications Radar

The AD8302 is a fully integrated system for measuring gain/loss and phase in numerous receive, transmit, and instrumentation applications. It requires few external components and a single supply of 2.7 V–5.5 V. The ac-coupled input signals can range from –60 dBm to 0 dBm in a 50 Ω system, from low frequencies up to 2.7 GHz. The outputs provide an accurate measurement of either gain or loss over a ±30 dB range scaled to 30 mV/dB, and of phase over a 0°–180° range scaled to 10 mV/degree. Both subsystems have an output bandwidth of 30 MHz, which may optionally be reduced by the addition of external filter capacitors. The AD8302 can be used in controller mode to force the gain and phase of a signal chain toward predetermined setpoints. The AD8302 comprises a closely matched pair of demodulating logarithmic amplifiers, each having a 60 dB measurement range. By taking the difference of their outputs, a measurement of the magnitude ratio or gain between the two input signals is available. These signals may even be at different frequencies, allowing the measurement of conversion gain or loss. The AD8302 may be used to determine absolute signal level by applying the unknown signal to one input and a calibrated ac reference signal to the other. With the output stage feedback connection disabled, a comparator may be realized, using the setpoint pins MSET and PSET to program the thresholds.The signal inputs are single-ended, allowing them to be matched and connected directly to a directional coupler. Their input impedance is nominally 3 kΩ at low frequencies. The AD8302 includes a phase detector of the multiplier type, but with precise phase balance driven by the fully limited signals appearing at the outputs of the two logarithmic amplifiers. Thus, the phase accuracy measurement is independent of signal level over a wide range. The phase and gain output voltages are simultaneously available at loadable ground referenced outputs over the standard output range of 0 V to 1.8 V. The output drivers can source or sink up to 8 mA. A loadable, stable reference voltage of 1.8 V is available for precise repositioning of the output range by the user. In controller applications, the connection between the gain output pin VMAG and the setpoint control pin MSET is broken. The desired setpoint is presented to MSET and the VMAG control signal drives an appropriate external variable gain device. Likewise, the feedback path between the phase output pin VPHS and its setpoint control pin PSET may be broken to allow operation as a phase controller. The AD8302 is fabricated on Analog Devices’ proprietary, high performance 25 GHz SOI complementary bipolar IC process. It is available in a 14-lead TSSOP package and operates over a –40°C to +85°C temperature range. An evaluation board is available.

The ADF4360-8 is an integrated integer-N synthesizer and voltagecontrolled oscillator (VCO). The ADF4360-8 center frequencyis set by external inductors. This allows a frequencyrange of between 65 MHz to 400 MHz. Control of all the on-chip registers is through a simple 3-wire interface. The device operates with a power supply ranging from 3.0 V to 3.6 V and can be powered down when not in use. 

The AD630 is a high precision balanced modulator/demodulatorthat combines a flexible commutating architecture with theaccuracy and temperature stability afforded by laser wafer trimmedthin film resistors. A network of on-board applications resistorsprovides precision closed-loop gains of ±1 and ±2 with 0.05%accuracy (AD630B). These resistors may also be used to accuratelyconfigure multiplexer gains of 1, 2, 3, or 4. External feedbackenables high gain or complex switched feedback topologies.The AD630 can be thought of as a precision op amp with twoindependent differential input stages and a precision comparatorthat is used to select the active front end. The rapid responsetime of this comparator coupled with the high slew rate and fastsettling of the linear amplifiers minimize switching distortion.The AD630 is used in precision signal processing and instrumentationapplications that require wide dynamic range. Whenused as a synchronous demodulator in a lock-in amplifierconfiguration, the AD630 can recover a small signal from100 dB of interfering noise (see the Lock-In AmplifierApplications section). Although optimized for operation up to1 kHz, the circuit is useful at frequencies up to several hundredkilohertz.Other features of the AD630 include pin programmable frequencycompensation; optional input bias current compensationresistors, common-mode and differential-offset voltage adjustment,and a channel status output that indicates which of thetwo differential inputs is active.Product Highlights The application flexibility of the AD630 makes it the best choice for applications that require precisely fixed gain, switched gain, multiplexing, integrating-switching functions, and high speed precision amplification. The 100 dB dynamic range of the AD630 exceeds that of any hybrid or IC balanced modulator/demodulator and is comparable to that of costly signal processing instruments. The op amp format of the AD630 ensures easy implementation of high gain or complex switched feedback functions. The application resistors facilitate the implementation of most common applications with no additional parts. The AD630 can be used as a 2-channel multiplexer with gains of 1, 2, 3, or 4. The channel separation of 100 dB at 10 kHz approaches the limit achievable with an empty IC package. Laser trimming of the comparator and amplifying channel offsets eliminate the need for external nulling in most cases.Applications Balanced modulation and demodulation Synchronous detection Phase detection Quadrature detection Phase sensitive detection Lock in amplification Square wave multiplication
