Description
The CMM3030-BD is a precision GaAs MMIC,
medium power amplifier and is part of Celeritek's family of
WideFiberTM products.
The CMM3030-BD optical driver amplifier gives
fiber optic system designers a unique combination of wide-
band frequency coverage, along with a flat response and very
low internal jitter. It is a precision PHEMT GaAs MMIC
medium power amplifier with +23 dBm @ P1dB. It operates
from 30 kHz to 30 GHz with a 9 dB linear gain. Low internal
jitter makes it especially well suited for high speed digital
data applications. Maximum output voltage is 7.5 V peak-to-
peak.
It is an excellent choice as a driver amplifier for
Lithium Niobate (Mach-Zehnder) external optical modulators,
to achieve high extinction ratio. Targeted for OC-192/STM64
metropolitan and long-haul dense wave-division multiplexed
optical networking applications and other high speed applica-
tions. The bit rate can be as high as 15 Gb/s to provide over-
head for forward error-correction algorithms. The bias voltage
can be adjusted to reduce the output voltage as needed.
CMM3030-BD amplifiers are shipped in Gel Pack
from Celeritek's foundry.

Die Attach and Bonding Procedures
Die Attach: Eutectic die attach is recommended. For eutec-
tic 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 (pre-
stressed); 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 CMM3030-BD, out-
put 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.
