The HMC907A is a GaAs MMIC pHEMT Distributed Power Amplifier die which operates between 0.2 and 22 GHz. This self-biased power amplifier provides 14 dB of gain, 41 dBm output IP3 and +28 dBm of output power at 1 dB gain compression while requiring only 350mA from a +10V supply. Gain flatness is excellent at ±0.7 dB from DC to 12 GHz making the HMC907A ideal for EW, ECM, Radar and test equipment applications. The HMC907A amplifier I/Os are internally matched to 50 Ohms facilitating integration into Mutli-Chip-Modules (MCMs). All data is taken with the chip connected via two 0.025mm (1 mil) wire bonds of minimal 0.31 mm (12 mils) length.ApplicationsTest InstrumentationMilitary & Space

The HMC908LC5 is a compact GaAs MCM I/Q downconverter in a leadless RoHS compliant SMT ceramic package. This device provides a small signal conversion gain of 11 dB with a noise figure of 2.2 dB and 25 dB of image rejection. The HMC908LC5 utilizes an LNA followed by an image reject mixer which is driven by an LO buffer amplifier. 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 HMC908LC5 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.ApplicationsPoint-to-Point and Point-to-Multi-Point RadioMilitary Radar, EW & ELINTSatellite CommunicationsMaritime & Mobile Radio

The HMC909LP4E Power Detector is designed for RF power measurement, and control applications for frequencies up to 5.8 GHz. The detector provides an accurate RMS representation of any broadband, single-ended RF/IF input signal. The output is a temperature compensated monotonic, representation of real signal power, measured with an input sensing range of 40 dB.The HMC909LP4E is ideally suited to those wide bandwidth, wide dynamic range applications, requiring repeatable measurement of real signal power, especially where RF/IF wave shape and/or crest factor change with time.The integration bandwidth of the HMC909LP4E is digitally programmable with the use of input pins SC I1-4 with a range of more than 4 decade. This allows the user to dynamically set the operation bandwidth providing the capability of handling different types of modulations on the same platform.HMC909LP4E features an internal op-amp at output stage, which provides for slope / intercept adjustments and enables controller application.ApplicationsLog –> Root-Mean-Square (RMS) ConversionReceived Signal Strength Indication (RSSI)Transmitter Signal Strength Indication (TSSI)RF Power Amplifier Efficiency ControlReceiver Automatic Gain ControlTransmitter Power Control
