The HMC571LC5 is a compact GaAs MMIC I/Q downconverter in a leadless RoHS compliant SMT package. This device provides a small signal conversion gain of 9 dB with a noise figure of 3.5 dB and 18 dB of image rejection across the frequency band. The HMC571LC5 utilizes an LNA followed by an image reject mixer which is driven by an active x2 multiplier. 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 HMC571LC5 is a much smaller alternative to hybrid style image reject mixer downconverter assemblies, and it eliminates the need for wire bonding by allowing the use of surface mount manufacturing techniques.APPLICATIONS Point-to-Point Point-to-Multi-Point Radio Military Radar, EW & ELINT Satellite Communications

The HMC600LP4(E) Logarithmic Detector/Controller converts RF signals at its input, to a proportional DC voltage at its output. The HMC600LP4(E) employs a successive compression topology which delivers extremely high dynamic range and conversion accuracy over a wide input frequency range. As the input power is increased, successive amplifiers move into saturation one by one creating an accurate approximation of the logarithm function.The output of a series of square law detectors is summed, converted into voltage domain and buffered to drive the LOGOUT output. For detection mode, the LOGOUT pin is shorted to the VSET input, and will provide a nominal logarithmic slope of 19mV/dB and an intercept of -95 dBm. The HMC600LP4(E) can also be used in the controller mode where an external voltage is applied to the VSET pin, to create an AGC or APC feedback loop.Applications Cellular/PCS/3G WiMAX, WiBro & Fixed Wireless Power Monitoring & Control Circuitry Receiver Signal Strength Indication (RSSI) Automatic Gain & Power Control
