The HMC8121 is an integrated E-band, gallium arsenide (GaAs), pseudomorphic (pHEMT), monolithic microwave integrated circuit (MMIC) variable gain amplifier and/or driver amplifier that operates from 81 GHz to 86 GHz. The HMC8121 provides up to 22 dB of gain, 20 dBm output P1dB, 27.5 dBm of OIP3, and 21 dBm of PSAT while requiring only 265 mA from a 4 V power supply. Two gain control voltages (VCTL1 and VCTL2) are provided to allow up to 17 dB of variable gain control. The HMC8121 exhibits excellent linearity and is optimized for E-band communications and high capacity wireless backhaul radio systems. All data is taken with the chip in a 50 Ω test fixture connected via a 3 mil wide × 0.05 mil thick × 7 mil long ribbon on each port.
Applications
- E-band communication systems
- High capacity wireless backhaul radio systems
- Test and measurement
