Splitter or pass-through configurable power divider

A method comprising:

• receiving, by a first input port of a circuit comprising one or more RF switches and a phase shifter, a first radio frequency (RF) signal;
• and
• performing, by the circuit, one or both of:
• splitting the first RF signal into a second RF signal and a third RF signal in response to the one or more RF switches having a first on-off configuration and the phase shifter applying a first phase shift, wherein the second RF signal and the third RF signal are substantially equal in power, wherein the second RF signal is routed to a first output port, and wherein the third RF signal is routed to a second output port;
• and
• passing the first RF signal to the second output port in response to the one or more RF switches having a second on-off configuration and the phase shifter applying a second phase shift, wherein the first on-off configuration is different than the second on-off configuration and the first phase shift is different than the second phase shift.

A Traffic Alert and Collision Avoidance System (TCAS) comprising:

• a receiver;
• a first antenna;
• a second antenna;
• and
• a transmitter comprising:
• an input port configured to receive a first radio frequency (RF) signal;
• a first output port connected to the first antenna;
• a second output port connected to the second antenna;
• a phase shifter;
• and
• one or more RF switches
• wherein the TCAS is configured to:
• split the first RF signal into a second RF signal and a third RF signal in response to the one or more RF switches having a first on-off configuration and the phase shifter applying a first phase shift, wherein the second RF signal and the third RF signal are substantially equal in power, wherein the second RF signal is routed to the first output port, and wherein the third RF signal is routed to the second output port;
• and
• pass the first RF signal to the second output port in response to the one or more RF switches having a second on-off configuration and the phase shifter applying a second phase shift, wherein the first on-off configuration is different than the second on-off configuration and the first phase shift is different than the second phase shift.
