Datasheet HMC8121 (Analog Devices)

81 GHz to 86 GHz, E-Band Variable Gain Amplifier Data Sheet HMC8121 FEATURES GENERAL DESCRIPTION Gain: 22 dB typical
The HMC8121 is an integrated E-band, gallium arsenide (GaAs),
Wide gain control range: 17 dB typical
pseudomorphic (pHEMT), monolithic microwave integrated
Output third-order intercept (OIP3): 27.5 dBm typical
circuit (MMIC), variable gain amplifier and/or driver amplifier
Output power for 1 dB compression (P1dB): 20 dBm typical
that operates from 81 GHz to 86 GHz. The HMC8121 provides up
Saturated output power (PSAT): 21 dBm typical
to 22 dB of gain, 20 dBm output P1dB, 27.5 dBm of OIP3, and
DC supply: 4 V at 265 mA
21 dBm of PSAT while requiring only 265 mA from a 4 V power
No external matching required
supply. Two gain control voltages (VCTL1 and VCTL2) are provided
Die size: 3.599 mm × 1.369 mm × 0.05 mm
to allow up to 17 dB of variable gain control. The HMC8121
