General Description
The HMC871LC5 is a GaAs MMIC PHEMT Distri-
buted Driver Amplifier packaged in a leadless 5x5mm
surface mount package. The amplifier operates
between DC and 20 GHz and provides 15 dB of
gain. The output swing cross point is adjustable
and saturated output swing is 4Vp-p. Gain flatness
is excellent at 0.5 dB as well as very low additive
RMS jitter of 300 fs for 10 Gbps operation. The
HMC871LC5 provides VSR and Gigabit Ethernet
designers with scalable power dissipation for
varying output drive requirements (<0.25W at Vout =
2.5 Vp-p and <0.6W at Vout = 4 Vp-p). The HMC871-
LC5 has a very wide supply (Vdd) operating range
from +5V to +8V and the I/Os are internally matched to
50 Ohms.
