The ADG901/ADG902 are wideband switches that use a complementary metal-oxide semiconductor (CMOS) process to provide high isolation and low insertion loss to 1 GHz. The ADG901 is an absorptive (matched) switch with 50 ? terminated shunt legs, while the ADG902 is a reflective switch. These devices are designed such that the isolation is high over the dc to 1 GHz frequency range. These switches enable the user to pass dc signals up to 0.5 V without the use of a dc blocking capacitor. They have on-board CMOS control logic, thus eliminating the need for external controlling circuitry. The control inputs are both CMOS and LVTTL compatible. The low power consumption of these CMOS devices makes them ideally suited to wireless applications and general-purpose high frequency switching.Product Highlights 40 dB Off Isolation at 1 GHz 0.8 dB Insertion Loss at 1 GHz 17 dBm P1dB at 1 GHzApplications Wireless communications General purpose RF switching Dual-band applications High speed filter selection Digital transceiver front-end switch IF switching Tuner modules Antenna diversity switching list

The HMC764LP6CE is a fully functioned Fractional-N Phase-Locked-Loop (PLL) with an Integrated Voltage Controlled Oscillator (VCO). The input reference frequency range is 100 kHz to 220 MHz while the advanced delta-sigma modulator design in the fractional PLL allows both ultra-fine step sizes and very low spurious products. The highly integrated structure provides excellent phase noise performance over temperature, shock and process. The HMC764LP6CE is packaged in a leadless QFN 6 x 6 mm surface mount package. The output power is 15 dBm typical, making the HMC764LP6CE ideal for driving the LO port of many of Hittite’s Hi Linearity and I/Q mixer products.For theory of operation and register map refer to the 'PLLs w/ Integrated VCO - Microwave VCOs' Operating Guide.Applications VSAT Radio Point-to-Point / Multi-Point Radio Test Equipment & Industrial Control Military End-Use Phased Array Applications

The HMC770LP4BE is a GaAs pHEMT Differential Gain Block MMIC amplifier covering 40 MHz to 1 GHz and packaged in a 4x4 mm plastic QFN SMT package. This versatile amplifier can be used as a cascadable IF or RF gain stage in both 50 Ohm and 75 Ohm applications. The HMC770LP4BE delivers 16 dB gain, and +40 dBm output, with only 2.5 dB noise figure.Differential I/Os make this amplifier ideal for transimpedance and SAW filter applications, and in transceivers where the IF path must be handled differentially for improved noise performance.

The AD8312 is a complete, low cost subsystem for the measurement of RF signals in the frequency range of 50 MHz to 3.5 GHz. It has a typical dynamic range of 45 dB and is intended for use in a wide variety of cellular handsets and other wireless devices. It provides a wider dynamic range and better accuracy than possible using discrete diode detectors. In particular, its temperature stability is excellent over the full operating range of −40°C to +85°C.Its high sensitivity allows measurement at low power levels, thus reducing the amount of power that needs to be coupled to the detector. It is essentially a voltage-responding device, with a typical signal range of 1.25 mV to 224 mV rms or −45 dBm to 0 dBm, referencing 50 Ω.For convenience, the signal is internally ac-coupled, using a 5 pF capacitor to a load of 3 kΩ in shunt with 1.3 pF. This high-pass coupling, with a corner at approximately 16 MHz, determines the lowest operating frequency. Therefore, the source may be dc grounded.The AD8312 output, VOUT, increases from close to ground to about 1.2 V because the input signal level increases from 1.25 mV to 224 mV. A capacitor may be connected between the VOUT and CFLT pins when it is desirable to increase the time interval over which averaging of the input waveform occurs.The AD8312 is available in a 6-ball, 1.0 mm × 1.5 mm, wafer-level chip scale package and consumes 4.2 mA from a 2.7 V to 5.5 V supply.Applications Cellular handsets (GSM, CDMA, WCDMA) RSSI and TSSI for wireless terminal devices Transmitter power measurement

The AD8364 is a true rms, responding, dual-channel RF powermeasurement subsystem for the precise measurement and controlof signal power. The flexibility of the AD8364 allows communicationssystems, such as RF power amplifiers and radio transceiverAGC circuits, to be monitored and controlled with ease. Operatingon a single 5 V supply, each channel is fully specified for operationup to 2.7 GHz over a dynamic range of 60 dB. The AD8364provides accurately scaled, independent, rms outputs of both RFmeasurement channels. Difference output ports, which measurethe difference between the two channels, are also available. Theon-chip channel matching makes the rms channel differenceoutputs extremely stable with temperature and process variations.The device also includes a useful temperature sensor with anaccurately scaled voltage proportional to temperature, specifiedover the device operating temperature range. The AD8364 canbe used with input signals having rms values from −55 dBm to+5 dBm referred to 50 Ω and large crest factors with noaccuracy degradation. Integrated in the AD8364 are two matched AD8362 channels(see the AD8362 data sheet for more information) with improvedtemperature performance and reduced log conformance ripple.Enhancements include improved temperature performance andreduced log-conformance ripple compared to the AD8362. On-chipwide bandwidth output operational amplifiers are connectedto accom-modate flexible configurations that support manysystem solutions.The device can easily be configured to provide four rmsmeasurements simultaneously. Linear-in-dB rms measurementsare supplied at OUTA and OUTB, with conveniently scaledslopes of 50 mV/dB. The rms difference between OUTA andOUTB is available as differential or single-ended signals atOUTP and OUTN. An optional voltage applied to VLVLprovides a common mode reference level to offset OUTP andOUTN above ground.The AD8364 is supplied in a 32-lead, 5 mm × 5 mm LFCSP, forthe operating temperature of –40°C to +85°C.Applications Wireless infrastructure power amplifier linearization/control Antenna VSWR monitor Gain and power control and measurement Transmitter signal strength indication (TSSI) Dual-channel wireless infrastructure radios
