Abstract
A transmitting/receiving circuit includes, in part, at least one transceiver, and at least two receiving channels forming a diversity receiver. One of the receiving channels includes, in part, a saw filter, an amplifier, and a frequency converter. The other receiving channel includes, in part, an amplifier, a frequency converter, and a received signal strength indicator (RSSI) adapted to detect signals transmitted by the transceiver. The RSSI is optionally coupled to an input terminal of its associated amplifier. The receiver further includes, in part, at least one processor operative to combine signals processed through the first and second receiving channels using a weight the processor assigns to the signal received by the second receiving channel in accordance with a strength of the blocker signal that the RSSI detects. The second receiving channel optionally includes an RSSI.
