GaAs IC 2 Watt High Linearity
SPDT Switch DC–2 GHz
Features
■ High Linearity (48 dBm IP3 @ 0.9 GHz)
■ Low Insertion Loss (0.35 dB @ 0.9 GHz)
■ Antenna Changeover and T/R Cellular
■ Ultra Miniature SOT-6 Lead Package
Operating Characteristics at 25°C (0, -5 V)
1. All measurements made in a 50 Ω system, unless otherwise specified.
2. DC = 300 kHz.
3. Insertion loss changes by 0.003 dB/°C.
4. Insertion loss state.
5. Video feedthru measured with 1 ns risetime pulse and 500 MHz bandwidth.
Description
The AS128-73 is a FET IC high power SPDT switch in a
SOT-6 plastic package. This switch is designed for use
where extremely high linearity, low insertion loss and
ultraminiature package size are required. It can be
controlled with positive, negative or a combination of both
voltages. Some standard implementations include
antenna changeover, T/R and diversity switching over
2 W. The AS128-73 switch can be used in many analog
and digital wireless communication systems including
cellular applications.
