Wideband Driver Amplifiers
AMZ-40
The AMZ-40 driver amplifier is a wideband, 100 kHz to 40 GHz amplifier intended for use in
broadband microwave and high data rate systems. The AMZ-40 is a 3-stage high output power
modulator driver amplifier that can provide up to +23 dBm saturated output (9 Vpp in a 50 
system) with a 40 Gb/s input signal. The small footprint, high output voltage swing and very
low DC power consumption (typ. <1.6 W) makes the AMZ-40 an excellent choice for 40 Gb/s
optical, test and measurement and general purpose use.
