The HMC197 is a GaAs MMIC SOT26 SPDT switch from Hittite that operates from DC to 3 GHz with low insertion loss and ultra small package. The device is ideal for 900 MHz, 1.8-2.2 GHz and 2.4 GHz ISM applications with insertion loss less than 1 dB.
The HMC197 is a GaAs MMIC single-pole double-throw (SPDT) switch designed for general switching applications requiring very low insertion loss and small size. It operates over a frequency range of DC to 3.0 GHz, making it especially suited for ISM bands such as 900 MHz, 1.8 - 2.2 GHz, and 2.4 GHz with less than 1 dB loss.
The device features an ultra-small SOT26 plastic package and is compatible with most CMOS & TTL logic families. It provides exceptional insertion loss performance ideal for filter and receiver switching, where RF ports act as reflective shorts when off. The control voltages require minimal DC current.
