The HMC261 chip is a GaAs MMIC distributed amplifier which covers the frequency range of 20 to 40 GHz. The chip can easily be integrated into Multi-Chip Modules (MCMs) due to its small (2.21 mm2) size. The chip utilizes a GaAs PHEMT process, operating from a single bias supply of + 3 to +4V with a P1dB output power of +12 dBm. This amplifier can be used in microwave & millimeter wave point-to-point radios, Local Multi-Point Distribution Systems (LMDS), VSAT, and other SATCOM applications. All data is with the chip in a 50 ohm test fixture connected via 0.025 mm (1 mil) diameter wire bonds of minimal length 0.31 mm (<12 mils). The HMC261 may be used to drive the LOs of HMC mixers such as the HMC203 or HMC259.
