RF switches are utilized to route RF signals, through one or more signal paths. Peregrine’s portfolio of UltraCMOS® RF switches vary in complexity and performance depending on the design of the application. For mobile handsets, Peregrine's existing switch products offer up to 16 RF signal paths with integrated digital bus support and onboard voltage regulation. Peregrine's broadband and general-purpose RF switches deliver an industry-leading combination of insertion loss, isolation, linearity and settling time, while routing RF signals to their respective transmit or receive paths. These attributes are important to OEMs of DTVs, set top box, cable infrastructure, test-and-measurement (T&M) equipment and high-performance wireless applications to replace legacy mechanical relays and GaAs-based designs.
Peregrine’s RF switches cover most of the frequency spectrum, from the low-end DC range of 0 Hz to the high-frequency range of greater than 40 GHz. RF engineers appreciate the breadth of choice Peregrine’s RF components deliver by combining high-performance RF, analog, passive elements, and digital functions on a single chip. The complete product line, which has shipped multibillion units, spanning SPST, SPDT, SP4T and higher throw count switches that feature high linearity, high isolation, high electrostatic discharge (ESD) ratings, low insertion loss, low phase noise and small form factors.
