Abstract

Methods and systems for an on-chip and/or on-package T/R switch and antenna are disclosed and may include selectively coupling one or more low noise amplifiers (LNAs) and/or one or more power amplifiers (PAs) to one or more ports of a multi-port distributed antenna utilizing configurable transmit/receive (T/R) switches integrated on a chip with the LNAs and PAs. The LNAs and PAs may be impedance matched to the antenna by coupling them to a port based on a characteristic impedance at the port. The T/R switches may be integrated on a package to which the chip may be coupled. The signals transmitted and received by the antenna may be time division duplexed. The antenna, which may include a microstrip antenna, may be integrated on the chip or the package. The LNA and the PA may be coupled to different ports on the antenna via the T/R switches.
