The HMC1094LP3E Logarithmic Detector converts RF signals at its input, to a proportional DC voltage at its output. The HMC1094LP3E employs successive compression topology which delivers high dynamic range over a wide input frequency range. As the input power is increased, successive amplifiers move into saturation one by one creating an approximation of the logarithm function. The output of a series of detectors is summed, converted into the voltage domain and buffered to drive the LOGOUT output. The HMC1094LP3E provides a nominal logarithmic slope of +18 mV/dB and an intercept of -113 dBm at 23 GHz.

The image reject mixer eliminates the need for a filter following the LNA, and removes thermal noise at the image frequency.I and Q mixer outputs are provided and an external 90? hybrid is needed to select the required sideband. The HMC951B is a much smaller alternative to hybrid style image reject mixer downconverter assemblies, and is compatible with surface mount manufacturing techniques.Applications Point-to-Point &?Point-to-Multi-Point Radio Military Radar, EW & ELINT Satellite Communications

The HMC985ALP4KE is an absorptive VoltageVariable Attenuator (VVA) which operates from 10- 40 GHz and is ideal in designs where an analogDC control signal must be used to control RF signallevels over a 35 dB dynamic range. It features twoshunt-type attenuators which are controlled by twoanalog voltages, Vctl1 and Vctl2. Optimum linearityperformance of the attenuator is achieved by firstvarying Vctl1 of the first attenuation stage from -5V to0V with Vctl2 fixed at -5V. The control voltage of thesecond attenuation stage, Vctl2, should then be variedfrom -5V to 0V with Vctl1 fixed at 0V.If the Vctl1 and Vctl2 pins are connected together it ispossible to achieve the full analog attenuation rangewith only a small degradation in input IP3 performance.Applications include AGC circuits and temperaturecompensation of multiple gain stages in microwavepoint-to-point and VSAT radios.Applications Point-to-Point Radio VSAT Radio Test Instrumentation Microwave Sensors Military, ECM & Radar
