Preliminary Data Sheet
FMA501
OC-192 MODULATOR DRIVER AMPLIFIER
• FEATURES
♦ DC – 20 GHz Frequency Bandwidth
♦ 17dB Small Signal Gain
♦ 8 Vpp Output Voltage
♦ -12 dB input/output return loss
♦ Chip Size: 1.18 x 2.3 mm
♦ Minimal Group Delay Variation
• DESCRIPTION AND APPLICATIONS
The Filtronic Solid State FMA501 is a medium power pHEMT amplifier that operates from DC to
20 GHz. This nine-stage travelling wave amplifier provides 17 dB nominal small signal gain and 8
V peak-to-peak NRZ output at bit rates to 12.5 Gb/sec. The FMA501 is designed as the output stage
for OC-192 MZ modulator driver amplifiers for optical data communication applications, and can be
cascaded with the FMA500 Pre-Driver MMIC to provide 30 dB of voltage gain.
