发明名称 INDEPENDENT GAIN CONTROL FOR MULTIPLE RECEIVE CIRCUITS CONCURRENTLY PROCESSING DIFFERENT TRANSMITTED SIGNALS
摘要 Techniques for simultaneously receiving multiple transmitted signals with independent gain control are disclosed. In an exemplary design, an apparatus (e.g., a wireless device, an integrated circuit, etc.) includes a low noise amplifier (LNA) and first and second receive circuits. The LNA amplifies a receiver input signal and provides (i) a first amplified signal for a first set of at least one transmitted signal being received and (ii) a second amplified signal for a second set of at least one transmitted signal being received. The first receive circuit scales the first amplified signal based on a first adjustable gain selected for the first set of transmitted signal(s). The second receive circuit scales the second amplified signal based on a second adjustable gain selected for the second set of transmitted signal(s). The first and second adjustable gains may be independently selected, e.g., based on the received powers of the transmitted signals.

主权项 1. An apparatus comprising: a low noise amplifier (LNA) configured to simultaneously provide a first amplified signal on a first output for a first set of at least one transmitted signal being received and a second amplified signal on a second output for a second set of at least one transmitted signal being received; a first receive circuit configured to scale the first amplified signal based on a first adjustable gain; and a second receive circuit configured to scale the second amplified signal based on a second adjustable gain.
