Description

Millitech series PDT broadband single-pole, double-throw (SPDT) PIN switches are available in seven waveguide bands from 18 to 100 GHz.

They are ideally suited for load switching and as duplexers and receiver protectors, offering wide bandwidth, high isolation, fast switching speeds, and low insertion loss. All switches are offered with integrated drivers, and can be operated with a standard TTL input.

Series PDT Y-configuration switches can be optimized for wide bandwidth (up to 10 GHz) or for improved isolation and insertion loss over smaller sub-bands.

Series PDT I-configuration switches are available in select commonly used bands. These offer fast, symmetrical switching speeds, increased isolation, and decreased insertion loss.

Millitech also offers series PSP single-pole, single-throw (SPST) switches and series PSH high speed switches. Please contact Millitech for information on series PS3 (SP3T) and PS4 (SP4T) models.

*1 - Narrow bandwidth units may be optimized for return loss and isolation, contact Millitech for customization details.
*2 - See figure 1 explanation of switching speeds.
*3 - Series PDT switches require both listed control voltages, as well as a TTL input to control the state.
*4 - Negative voltage required to maintain stated isolation varies with incident RF power, consult Millitech for additional details.
