The HMC871LC5 is a GaAs MMIC PHEMT Distributed 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= 2.5VP-Pand <0.6W at VOUT= 4VP-P). The HMC871LC5 has a very wide supply (VDD) operating range from +5V to +8V and the I/Os are internally matched to 50 OhmsAPPLICATIONSSONET OC-192 & SDH-STM-64 Transmission Systems10 GbE Transmitters10 Gbps VSR ModulesPre-driver for 40 Gbps DQPSK ModulesBroadband Gain Block for Test & Measurement Equipment
