SYSTEM AND METHOD FOR TDD-FDD DUPLEXING IN A RADIO ARCHITECTURE

Document Type and Number:

WIPO Patent Application WO/2016/119520

Kind Code:

A1

Abstract:

A reconfigurable TDD-FDD multiplexer operates in a TDD mode and a FDD mode. The TDD-FDD multiplexer includes an interdigital quadruplexer in series with a one-pole three-throw RF switch. The interdigital quadruplexer includes of two V-band filters, connectable to a transmitter and a receiver, respectively, for TDD mode duplexing, and two E-band filters, connectable to a transmitter and a receiver, respectively, for FDD mode duplexing. The E-band filters include an E-band transmitting filter that passes an E-band transmitting frequency band, and an E-band receiving filter that passes for an E-band receiving frequency band offset from the E-band transmitting frequency band. Switching between the V-band receiving filter and V-band transmitting filter enables TDD duplexing functionality at V-band frequencies. Switching to the two E-band filters enables FDD duplexing functionality at E-band frequencies.
