The Asartech PZ0503 is a three-channel RF detector for microwave power monitoring. Three identical channels combine amplification and detection across 6–18 GHz, providing a compact module for monitoring multiple RF signals.
An RS-485 interface provides readout of RF power levels and module temperature. The detector is suitable for microwave radio power control, radar applications and test equipment, with a frequency-dependent dynamic range and a maximum input level of +3 dBm.
