HMC405 InGaP HBT GAIN BLOCK MMIC AMPLIFIER, DC - 10 GHz v03.0109 General Description Features Functional Diagram The HMC405 die is a GaAs InGaP Heterojunction Bipolar Transistor (HBT) Gain Block MMIC DC to 10 GHz amplifi er. This amplifi er can be used as either a cascadable 50 Ohm gain stage or to drive the LO of HMC mixers with up to +17 dBm output power. The HMC405 offers 16 dB of gain and an output IP3 of +32 dBm while requiring only 50 mA from a +5V supply. The Darlington feedback pair used results in reduced sensitivity to normal process variations and yields excellent gain stability over temperature while requiring a minimal number of external bias components. The HMC405 can easily be integrated into Multi-Chip-Modules (MCMs) due to its small (0.22mm 2 ) size. All data is with the chip in a 50 Ohm test fi xture connected via 0.025mm (1 mil) diameter wire bonds of minimal length 0.5mm (20 mils). Gain: 16 dB P1dB Output Power: +13 dBm Stable Gain Over Temperature 50 Ohm I/O’s Small Size: 0.38 x 0.58 x 0.1 mm Typical Applications An excellent cascadable 50 Ohm Gain Block or LO Driver for: • Microwave & VSAT Radios • Test Equipment • Military EW, ECM, C 3 I • Space Telecom
