DESCRIPTION AND APPLICATIONS
The Filtronic Solid State FMA500 is a high-gain pre-driver pHEMT amplifier that operates from DC
to 23 GHz. This five-stage travelling wave amplifier provides 13 dB nominal small signal gain and
4 V peak-to-peak NRZ output at bit rates to 12.5 Gb/sec. The FMA500 is designed as the pre-driver
stage for OC-192 MZ modulator driver amplifiers for optical data communication applications, and
can be cascaded with the FMA501 Driver MMIC to provide 30 dB of voltage gain. The FMA500
can also be used as an EA driver amplifier or as a transimpedance amplifier (TIA) for photoreceiver
applications.

Notes:
• Operating conditions that exceed the Absolute Maximum Ratings could result in permanent damage to the device.
• Recommended Continuous Operating Limits should be observed for reliable device operation.
• This PHEMT is susceptible to damage from Electrostatic Discharge. Proper precautions should be used when handling these
devices.

Notes:
• Apply VGG first, then VGC and VDD.
• Disconnect VGC first, then VDD and VGG when turning off.
• Recommended lead bond technique is thermocompression wedge bonding with 0.001” (25µm) diameter wire. The
bond tool force shall be 35-38 gram. Bonding stage temperature shall be 230-240°C, heated tool (150-160°C) is
recommended. Ultrasonic bonding is not recommended.
• The recommended die attach is Ablebond silver epoxy, the stabilize bake temperature is set at 150°C for 45 minutes.
• Bond on bond or stitch bonds acceptable.
• Conductor over conductor acceptable. Conductors must not short.

HANDLING PRECAUTIONS
To avoid damage to the devices care should be exercised during handling. Proper Electrostatic
Discharge (ESD) precautions should be observed at all stages of storage, handling, assembly, and
testing. These devices should be treated as Class 1A (0-500 V). Further information on ESD control
measures can be found in MIL-STD-1686 and MIL-HDBK-263.
All information and specifications are subject to change without notice.
