T/R switch design for short-range measurements, part 6.1A [PDF]
The positive intrinsic negative (PIN) diode switch which is designed to protect the receiver from burnout or damage on transmission and channel the echo signal to the receiver on reception is outlined. The receiver must be protected firmly.

Frequency Reconfigurable Antenna using PIN Diodes
International Journal of Engineering and Advanced Technology, 2019 With the increase in wireless applications, there is a need for compact antennas that adapt their behavior with changing system requirements or environmental conditions. Here adapt implies the antenna should be able to alter operating frequencies, impedance bandwidths, polarizations, radiation patterns.

The phase-switched screen [PDF]
, 2004 Conventional (passive) radar-absorbent materials operate either by phase cancellation or by absorbing incident electromagnetic energy and converting it into heat. This paper examines a new type of active "absorber," called the phase-switched screen (PSS).
