Abstract
A radio frequency circuit assembly is disclosed. An example radio frequency circuit assembly comprises a plurality of antenna switch modules, where each antenna switch module is coupled to a transmit signal contact via a transmit band filter, a plurality of receive signal contacts via a respective plurality of receive band filters, and a plurality of antenna contacts. The antenna switch modules are configured such that each of the plurality of antenna contacts are selectively coupled to the transmit signal contact.
