Description
The CMM0335 is a highly efficient, 6V power
amplifier intended for use in portable cellular handsets and
datacom products operating in the SMR, GSM and 902–928
MHz ISM bands. As a pin-compatible member of the new
Triniti DX
amplifier family, the CMM0335 offers maxi-
mum performance and flexibility.The CMM0335 is packaged
in a low-cost, space efficient SO-8 power package that gives
excellent electrical stability and thermal handling performance
with a R
Θ
of less than 18° C/W. The part is designed to
require minimal external circuitry for bias matching, simplify-
ing design and keeping board space and cost to a minimum.
