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 10 dB linear gain. Low inter-
nal 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 external optical modulators, to acheive high
extinction ratio. Targeted for OC-192 and other high speed
applications, the bit rate can be as high as 15 Gb/s. 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.
