Description
The AP640R5-A3 is a broadband millimeterwave singlepole double-throw (SPDT) switch in a rugged surface
mount package which is compatible with high-volume
solder installation. Based on PIN diode MMIC technology,
the switch is designed for use in millimeterwave
communication and sensor systems when low loss and
high linearity are required. Typical applications are
transmit/receive function for TDD systems or switching
between signal paths.The robust ceramic surface mount
package provides excellent electrical performance and a
high degree of environmental protection for long-term
reliability. All switches are screened at the operating
frequencies prior to shipment for guaranteed
performance. Switch is targeted for high-volume
broadband applications such as satellite and fixed wireless
systems.
