Description
The CMM3030-BD is a precision GaAs MMIC,
medium power amplifier and is part of Celeritek’s family of
WideFiber™ 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.
