GaAs MMIC SP4T Non-Reflective Switch, DC - 18 GHz

Manufactured by:

Product Details

The HMC641A is a broadband non-reflective GaAs PHEMT SP4T switch chip. Covering DC to 18 GHz, this switch offers high isolation and low insertion loss and extends the frequency coverage of ADI’s SP4T switch product line. This switch also includes an on board binary decoder circuit which reduces the number of required logic control lines to two. The switch operates using a negative control voltage of 0/-5V, and requires a fixed Vss bias of -5V. All data is tested with the chip in a 50 Ohm test fixture connected via one 3.0 x 0.5 mil gold ribbon of minimal length on each RF port.
