CMM3020-BD
Description
The CMM3020-BD is a precision GaAs MMIC,
medium power amplifier and is part of Celeritek’s family of
WideFiber™ products.
The CMM3020-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 Ion/Implanted GaAs RF IC medi-
um power amplifier with +23 dBm @ P1dB (Typ). It operates
from 30 kHz to 20 GHz with a 10 dB linear gain. Low internal
jitter makes it especially well suited for high speed digital data
applications. Typical output voltage is 7.5 V peak-to-peak.
It is an excellent choice for driving Lithium Niobate
external optical modulators, where a high extinction ratio is
necessary. Targeted for OC-192 and other high speed applica-
tions, the bit rate can be as high as 15 Gb/s. The bias voltage
can be adjusted to reduce the output voltage as needed.
CMM3020-BD amplifiers are shipped in Gel Pack
from Celeritek’s foundry.
