RADIO FRONT END HAVING REDUCED DIVERSITY SWITCH LINEARITY REQUIREMENT
First Claim
1. A radio front end comprising:
- a diversity switch module adapted to selectively route diversity receive (RX) signals to transceiver circuitry from diversity antenna switch circuitry coupled to at least one diversity antenna port; and
ultrahigh band (UHB) switch circuitry adapted to;
selectively route UHB transmit (TX) signals from power amplifier and switch circuitry to either a UHB antenna port or to the at least one diversity antenna port; and
selectively route UHB RX signals from either the UHB antenna port or from the at least one diversity antenna port to the transceiver circuitry, wherein the UHB RX signals include band 7 (B7) wherein linearity of the UHB switch circuitry is greater than linearity of the diversity switch module.

Abstract
A radio front end that includes a diversity switch module adapted to route diversity receive (RX) signals to transceiver circuitry from diversity antenna switch circuitry coupled to at least one diversity antenna port is disclosed. The radio front end further includes ultrahigh band (UHB) switch circuitry adapted to route UHB transmit (TX) signals from power amplifier and switch circuitry to a UHB antenna port and/or to at least one diversity antenna port. The UHB switch circuitry is also adapted to route UHB RX signals from the UHB antenna port and/or to at least one antenna port to the transceiver circuitry, wherein the UHB RX signals include band 7 (B7) wherein linearity of the UHB switch circuitry is greater than linearity of the diversity switch module.
