The document introduces the features and characteristics of the HMC245QS16 model. It is a low-cost non-reflective SP3T switch suitable for frequencies from DC to 3.5 GHz. The switch features low insertion loss, high isolation, and an integrated 2:3 TTL decoder.
The HMC245QS16 is a low-cost, non-reflective SP3T switch designed for frequencies from DC to 3.5 GHz. It features a 16-lead QSOP surface mount package and offers low insertion loss of 0.5 dB at 2.0 GHz. The device includes an integrated 2:3 TTL/CMOS compatible decoder, requiring only two control lines and a single +5V bias to select the RF path, replacing the six control lines typically needed for GaAs SP3T switches.
