RF LDMOS Wideband Integrated
Power Amplifiers
The MW7IC2750N wideband integrated circuit is designed with on--chip
matching that makes it usable from 2300 -- 2700 MHz. This multi -- stage
structure is rated for 26 to 32 Volt operation and covers all typical cellular
base station modulation formats.
