Die size: 3.599 mm × 1.369 mm × 0.05 mm 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 × 0.5 mil thick × 7 mil long ribbon
on each port. APPLICATIONS …
