Description
The CMM2030-BD is a precision GaAs MMIC,
medium power amplifier and is part of Celeritek’s family of
WideFiber products for optical communications applica-
tions.
The CMM2030-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 +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 applica-
tions 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.
