Description
The CMM2030-BD is a precision GaAs MMIC, medium power amplifier and is part of Celeritek's family of WideFiberTM products for optical communications applications. The CMM2030-BD optical driver amplifier gives fiber optic system designers a unique combination of wideband frequency coverage, along with a flat response and very low internal jitter. It is a precision PHEMT GaAs MMIC medium power amplifier with +18 dBm @ P1dB. It operates from 30 kHz to 32 GHz with 12 dB linear gain. Low internal
jitter makes it especially well suited for high speed digital data applications. It is an excellent choice as an input stage amplifier for Lithium Niobate (Mach-Zehnder) external modulator driver amplifiers for OC-192/STM64 metropolitan and long-haul dense wave-division multiplexed optical networking applications and other high speed applications. When used as an amplifier to drive Celeritek's CMM3030-BD as much as 7.5 V peak-to-peak can be achieved. CMM2030-BD amplifiers are shipped in Gel Pack from Celeritek's foundry.

Die Attach and Bonding Procedures
12 V -5 V 375 mA 3.0 W +175C -65C to +175C +320C +23 dBm
Die Attach: Eutectic die attach is recommended. For eutectic die attach: Preform: AuSn (80% Au, 20% Sn); Stage Temperature: 290C, 5C; Handling Tool: Tweezers; Time: 1 min or less. Wire Bonding: Wire Size: 0.7 to 1.0 mil in diameter (prestressed); Thermocompression bonding is preferred over thermosonic bonding. For thermocompression bonding: Stage Temperature: 250C; Bond Tip Temperature: 150C; Bonding Tip Pressure: 18 to 40 gms depending on size of wire.

Performance Optimization
Using the Gain-Ctl facility of the CMM2030-BD, output power may be increased by application of 1.2 to 1.8 Volts to the Bias Control pad. If the Gain-Ctl facility is not used, a fixed voltage at the Bias Control pad can be implemented by
connecting a off-chip parallel resistor to the pad which will lower the output voltage accordingly. If Bias Control voltage is decreased further than those lowest values given in the tables, both gain and output power will start to drop.
