Broadband High and Medium Power SPDT
Switch Family
The RFMD family of broadband single-pole double throw (SPDT) switches is designed for general purpose applications which require very low insertion loss and medium to high power handling capability. The RF3021 is a reflective high-power, high isolation switch featuring an on-chip inverter for single positive supply. The RF3023 and RF3024, reflective medium-power broadband SPDT switches, offer low insertion loss. Both switches are identical with the exception that their switching logic is reversed. The RF3025, a high-power broadband absorptive SPDT switch, features an on-chip inverter for single positive supply. Each switch is fabricated with 0.5µ GaAs pHEMT process and comes in a compact 3 x 3 mm or SC- 70 QFN package.
