Peregrine Semiconductor has introduced two new SP5T (single pole, five throw) RF switches designed for the next generation of high-power LTE public safety and military radios. The combination of the maker’s UltraCMOS and HaRP technologies allow the PE42850 and PE42851 to achieve 17 W of power handling, with high linearity.
HaRP technology enables 2fo/3fo harmonic performance of -90 dBc into a 1,15:1 VSWR in the PE42850, and -80 dBc into a 1,15:1 VSWR in the PE42851. These features, along with a high throw count, make the devices ideal for transmit/receive and filter-band switching applications in land mobile radios (LMRs).
The ICs feature low insertion loss of (RFC-RFx) 0,25 dB @ 520 MHz to reduce RF signal attenuation, resulting in less heat dissipation and improved performance. Their low typical power consumption of 130 μA helps to extend battery life.
High ESD performance of 1,5 kV HBM eases manufacturing and results in longer product life. In addition to SP5T, the switches can be configured as SP3T devices, giving designers the flexibility to use one switch in multiple locations, for multiple purposes throughout the RF signal chain.
