  • Multiple frequency RF transceiver
    Patent number: 5878332
    Abstract: An RF transceiver operable in two separate frequency bands has transmitter and receiver elements with broadband components to provide a flat frequency response across the two separate operating frequency bands. The broadband transmitting and receiving elements are utilized with other narrow band components which are designed for operating in either the first frequency band or the second frequency band. The use of common components for operating in both frequency bands reduces part count and cost along with reduced size and weight.

  • Low voltage input buffer
    Patent number: 5869985
    Abstract: A differential input buffer operable at power supply voltages below 3.0 V comprises first and second field effect transistors connected between a power supply and a current source as a differential pair in receiving input and input bar signals. Using enhancement mode field effect transistors and heterojunction bipolar transistors for a current source, a power supply voltage Vcc as low as 2 V is possible for circuit operation.
