SKY5A2204

Sky5® TX/RX Front-End Module with 15 Linear TRX Switch Ports for Quad-Band GSM/GPRS/EDGE

The SKY5A2204 Sky5® TX/RX FEM offers switching solutions for 4G/5G automotive and telematics NAD. Two power amplifiers (PAs) support quad-band GSM, GPRS, EDGE multi-slot operation and TD-SCDMA and TDD LTE transmission. The low band (LB) PA transmits in the GSM850/900 bands. The mid-band (MB) PA covers DCS1800, PCS1900, TD-SCDMA bands 34/39, and TDD LTE band 34/39. The SKY5A2204 is part of our Sky5® product portfolio.

The FEM facilitates flexible broadband RF switching using 15 transmit/receive (TRX) antenna switch ports, covering all 3G/4G/5G bands, from the 700 MHz range through the 2300 to 2700 MHz range.

In support of downlink inter-band CA, the TRX ports are partitioned into two independent switch blocks, including six LB ports and nine M/HB ports. Each switch block includes a forward directional coupler that may be monitored on the coupler port. For dual antenna application designs, the SKY5A2204 has dedicated LB and M/HB antenna ports. These ports provide the simultaneous LB and M/HB reception required for downlink CA.
