RF front-end circuitry with transistor and microelectromechanical multiple throw switches

Radio frequency (RF) front-end circuitry, comprising:

• a first multiple throw microelectromechanical switch (MTMEMS) having a first set of throw ports and a first pole port, wherein the first MTMEMS is configured to selectively couple the first pole port to a selected first MTMEMS throw port among the first set of throw ports;
• a second MTMEMS having a second set of throw ports and a second pole port, wherein the second MTMEMS is configured to selectively couple the second pole port to a selected second MTMEMS throw port among the second set of throw ports;
• and
• a multiple throw solid state transistor switch (MTSTS) having a third set of throw ports and a third pole port, wherein:
• a first selected MTSTS throw port in the third set of throw ports is coupled to the first pole port of the first MTMEMS;
• a second selected MTSTS throw port in the third set of throw ports is coupled to the second pole port of the second MTMEMS;
• and
• the MTSTS is configured to selectively couple the third pole port to any one of the third set of throw ports;
• and
• a control circuit configured to:
• maintain coupling between the first pole port and the selected first MTMEMS throw port when switching the third pole port from being coupled to the first selected MTSTS throw port among the third set of throw ports to another MTSTS throw port among the third set of throw ports;
• and
• maintain coupling between the second pole port and the selected second MTMEMS throw port when switching the third pole port from being coupled to the second selected MTSTS throw port among the third set of throw ports to another MTSTS throw port among the third set of throw ports.
