PHS Band 8 Watt Amplifier

FEATURES

• Bias Condition : 5.5 A @ +12 V, 20 mA @ -10 V

• Small Signal Gain : 48 dB

DESCRIPTION

The TA018-019-48-43 is a 8W power amplifier designed for high linearity applications in the 1.893 to 1.920

GHz frequency range. This amplifier utilizes high power devices that provide excellent linearity, high gain

and wide dynamic range. High efficiency operation is achieved by using advanced GaAs PHEMT devices.

APPLICATION : PHS base station
