Product Overview: Microwave Detectors: 10 MHz To 40 GHz Testing And Term Definition

Krytar manufactures microwave detectors using zero bias silicon schottky diodes and planar doped detector diodes. Testing and Term definition for performance of the two types are identical.

OPERATING FREQUENCY
Krytar tests operation performance of detectors using an Automatic Network Analyzer which currently has the ability to measure performance of Krytar Detectors to 40 GHz. Krytar offers two types of Detectors. 200 Series Zero Bias Schottky Detectors have a video bypass capacitance of 30 pF and operate from 10 MHz to 40 GHz. 300 Series Zero Bias Schottky Detectors have a video bypass capacitance of 3.0 pF and operate from 100 MHz to 40 GHz. 700 Series Planar Doped Barrier Detectors have a Video Bypass Capacitance of 3 pF and operate from 100 MHz to 40 GHz. 600 Series Planar Doped Barrier Detectors have a video bypass capacitance of 30 pF and operate from 10 MHz to 40 GHz. Note that a Video Bypass Capacitance of 3.0 pF will yield a risetime of less than 20 nanoseconds. 30 pF Video Bypass Capacitance will yield a longer risetime.

TANGENTIAL SENSITIVITY
Krytar manufactures detectors from schottky diodes which typically have a tangential sensitivty (TSS) of -57 dBm usually measured using an amplifier with a video bandwidth of 1.0 KHz and a Noise Figure of 3 dB. The amplifier presents an Impedance of 100 K ohms or more to the diode. TSS of a detector using these diodes produces an RF signal level that yields an 8 dB video output voltage to noise ratio.. Krytar Detectors use additional circuitry to provide state-of-the-art flat frequency response and very low VSWR. This drops the TSS of the Krytar Detector to approximately -46 dBM. Generally, Krytar detectors are comfortably used to detect signals of -40 dBm to 20 dBm.
