General Description
The HMC870LC5 is a GaAs MMIC pHEMT Distri-
buted Driver Amplifier packaged in a leadless 5x5 mm
surface mount package which operates between
DC and 20 GHz. The amplifier provides 17 dB of gain,
8Vp-p saturated output swing and features output
swing cross point adjustment. Gain flatness is excel-
lent at ±0.5 dB as well as very low additive RMS jitter
of 300 fs for 10 Gbps operation. HMC870LC5 prov-
ides Metro and Long Haul designers with scalable
power dissipation for varying output drive require-
ments. (<0.4W at Vout = 3.6 Vp-p and <1W at Vout
= 8.5 Vp-p) The HMC870LC5 has a very wide supply
(Vdd) operating range from +3.3V to +7V, and the RF
I/Os are internally matched to 50 Ohms.
