amplifier intended for use in portable cellular handsets and
datacom products operating in the AMPS, TACS/ETACS,
NMT 900 and 902–928 MHz ISM bands. As a pin-compatible
member of the new
Triniti DX
™
amplifier family, the
CMM0331 offers maximum performance and flexibility.The
CMM0331 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 circuit-
ry for bias matching, simplifying design and keeping board
space and cost to a minimum.
