MA1046-1
For 1.9 GHz - Power Amplifier
DESCRIPTION
The MA1046-1 is a 1.9 GHz band power
amplifier (Po = +3.1W), constructed by 3 stages
of GaAs MESFET, RF matching circuit, and DC
bias circuit. The shield cap is made of metal.
Input and Output impedances are designed to
50Ω.
FEATURES
Po = +35.0 dBm, Gain = +32 dB (min.) @1.9 GHz
Vd1, 2 = +6.0V, Vd3 = +10.0V
Vg1, 2 = –5.0V, Vg3 = 3.0V
APPLICATION
Power amplifier for PHS base station/Japan.
