The AD8344 is a high performance, broadband active mixer. It is well suited for demanding receive-channel applications thatrequire wide bandwidth on all ports and very low intermodulation distortion and noise figure.The AD8344 provides a typical conversion gain of 4.5 dB at 890 MHz. The integrated LO driver supports a 50 ? inputimpedance with a low LO drive level, helping to minimize external component count.The single-ended 50 ? broadband RF port allows for easy interfacing to both active devices and passive filters. The RFinput accepts input signals as large as 1.7 V p-p or 8.5 dBm (re: 50 ?) at P1dB.The open-collector differential outputs provide excellent balance and can be used with a differential filter or IF amplifier,such as the AD8369 or AD8351. These outputs may also be converted to a single-ended signal through the use of a matchingnetwork or a transformer (balun).When centered on the VPOS supply voltage, each of the differential outputs may swing2.5 V p-p.The AD8344 is fabricated on an Analog Devices proprietary, high performance SiGe IC process. The AD8344 is availablein a 16-lead LFCSP package. It operates over a ?40?C to +85?C temperature range.An evaluation board is also available.ApplicationsCellular base station receiversISM receiversRadio linksRF Instrumentation

The AD8362 is a true rms-responding power detector that has a 65 dB measurement range. It is intended for use in a variety of high frequency communication systems and in instrumentation requiring an accurate response to signal power. It is easy to use, requiring only a single supply of 5 V and a few capacitors. It operates from arbitrarily low frequencies to over 3.8 GHz and accepts inputs from ?52 dBm to +8 dBm with crest factors that are typical of quadrature amplitude modulation (QAM) and orthogonal frequency division multiplexing (OFDM) modulation schemes.The input signal is applied to a resistive ladder attenuator that comprises the input stage of a variable gain amplifier (VGA). The 12 tap points are smoothly interpolated using a proprietary technique to provide a continuously variable attenuator, which is controlled by a voltage applied to the VSET pin. The resulting signal is applied to a high performance broadband amplifier. Its output is measured by an accurate square-law detector cell. The fluctuating output is then filtered and compared with the output of an identical squarer, whose input is a fixed dc voltage applied to the VTGT pin, usually the accurate reference of 1.25 V pro-vided at the VREF pin.The difference in the outputs of these squaring cells is integrated in a high gain error amplifier, generating a voltage at the VOUT pin with rail-to-rail capabilities. In a controller mode, this low noise output can be used to vary the gain of a host system?s RF amplifier, thus balancing the setpoint against the input power. Optionally, the voltage at VSET can be a replica of the RF signal?s amplitude modulation, in which case the overall effect is to remove the modulation component prior to detection and low-pass filtering. The corner frequency of the averaging filter can be lowered without limit by adding an external capacitor at the CLPF pin. The AD8362 can be used to determine the true power of a high frequency signal having a complex low frequency modulation envelope, or simply as a low frequency rms volt-meter. The high-pass corner generated by its offset-nulling loop can be lowered by a capacitor added on the CHPF pin.Used as a power measurement device, VOUT is strapped to VSET. The output is then proportional to the logarithm of the rms value of the input. In other words, the reading is presented directly in decibels and is conveniently scaled 1 V per decade, or 50 mV/dB; other slopes are easily arranged. In controller modes, the voltage applied to VSET determines the power level required at the input to null the deviation from the setpoint. The output buffer can provide high load currents.The AD8362 has 1.3 mW power consumption when powered down by a logic high applied to the PWDN pin. It powers up within about 20 ?s to its nominal operating current of 20 mA at 25?C. The AD8362 is supplied in a 16-lead TSSOP for operation over the temperature range of ?40?C to +85?C.ApplicationsPower amplifier linearization/control loops Transmitter power controls Transmitter signal strength indication (TSSI) RF instrumentation
