RF LDMOS Wideband Integrated
Power Amplifiers
The MD8IC970N wideband integrated circuit is designed with on--chip
prematching that makes it usable from 136 to 940 MHz. This multi--stage
structure is rated for 26 to 32 Volt operation and covers all typical base station
modulation formats. This device has a 2--stage design with off--chip matching
for the input, interstage and output networks to cover the desired frequency
sub--band.
• Typical Two--Tone Performance: VDD1 = 28 Volts, VDD2 = 25 Volts,
IDQ1(A+B) = 60 mA, IDQ2(A+B) = 550 mA, Pout = 35 Watts Avg.
