In the specifically configured SOT-143 package, the PIN diodes are oriented to enable connection as a λ/4 switch with no external crossover connections. Transmitter SMP1322-011 Antenna DC Control Receiver SMP1322-017 λ/4 T/R Switch Design SMP1322-017 SOT-143 Low Inductance PIN Diode The SMP1322-017 utilizes the SMP1322 PIN diode chip in a customized SOT-143 plastic package designed for high isolation performance in a shunt connected switch. Its effective inductance, based on the 3 GHz isolation, is less than 0.2 nH. This diode is designed to work effectively as a shunt element in SPDT switches, covering the wireless frequencies from 900 MHz to beyond 2 GHz. Excellent performance is achievable when used in a quarter-wave T/R switch with the SMP1322-001 (SOT-23) or SMP1322-011 (SOD-323) PIN diode as the series connected diode. 4 13 2 4 3 1 2 43 12 Schematic Switch Connection Lead Configuration |
