PE42641MLBD-Z RF/IF and RFID

RF Switches are components used to control signals in radios and electronic systems. The PE42641MLBD-Z is a high performance, wideband RF switch with a broad frequency range, Tx and Rx paths, and high isolation that supports both wireless and wired communications.

Application Field

PE42641MLBD-Z is a single-pole, three-throw (SP3T) RF switch that can be used to support a wide range of applications. It is used in many consumer and commercial wireless devices to connect different antennas and components including GSM, CDMA, Wifi, Bluetooth, GPS, and FM bands. It can also be used for military and aerospace applications where high isolation and sheet performance is vital.

Working Principle

The PE42641MLBD-Z is an RF switch with high isolation and low insertion loss when operating in the 500MHz to 2700MHz frequency range, with >80dB isolation and < 0.3dB insertion loss across the entire frequency range. The switch is tolerant to a wide range of input voltage levels, can handle up to 0.5W maximum input power, and can accommodate a wide range of switching speeds. It has excellent linearity and efficient power handling characteristics.

The switch is built on a monolithic silicon structure and uses a two-layer, thermally-isolated metal-gate to achieve exceptional linearity and wide frequency performance. The metal gate is connected to the signal lines and switches the signal to the desired destination. It also offers high power handling capability across the entire temperature range.

The switch has a low profile footprint and is highly tolerant to ESD, withstanding ±4.5kV Human Body Model (HBM). The device also has a wide operating temperature range of -40°C to +105°C.

Conclusion

The PE42641MLBD-Z is an RF switch with high isolation and low insertion loss that supports a wide range of applications, from consumer to military and aerospace systems. The device has a two-layer, thermally-isolated metal-gate which offers excellent linearity and wide frequency performance. It is also highly tolerant to ESD and temperature variations.
