CXG7003FN

26 pin HSOF (Plastic)

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

Notes on Handling

GaAs MMICs are ESD sensitive devices. Special handling precautions are required.

Description

The CXG7003FN is a MMIC consisting of the

power amplifier, diversity antenna supported switch

and low noise down conversion mixer.

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

process featuring a single positive power supply

operation.

Features

• Diversity antenna supported switch

• Small mold package: 26-pin HSOF

<Power amplifier/antenna switch transmitter block >

• High power gain: Gp = 40dB Typ.

<Antenna switch receiver block/

low noise down conversion mixer>

(When no signal)

• High conversion gain: Gc = 19.5dB Typ. (f = 1.9GHz)

• Low distortion: Input IP3 = –12dBm Typ. (f = 1.9GHz)

• High image suppression ratio: IMR = 40dBc Typ.

(f = 1.9GHz)

• High 1/2 IF suppression ratio: 1/2IFR = 47dBc Typ.

(f = 1.9GHz)
