Power Amplifier/Antenna Switch + Low Noise Amplifier/Down Conversion Mixer for PHS

Description

The CXG1053FN is an MMIC consisting of the

power amplifier, antenna switch, low noise amplifier

and down conversion mixer.

This IC is designed using the Sony's GaAs J-FET

process featuring a single positive power supply

operation.

Features

• Small mold package: 26-pin HSOF

<Power amplifier/antenna switch transmitter block >

• High power gain: Gp = 39dB Typ.

<Antenna switch receiver block/

low noise amplifier>

(When no signal)

• Low noise: NF = 2.7dB Typ. (f = 1.9GHz)

<Down conversion mixer>

• High conversion gain: Gc = 9dB Typ. (f = 1.9GHz)

• Low distortion: Input IP3 = +1dBm Typ. (f = 1.9GHz)
