Broadband Detectors

Pacific Millimeter Products

Pacific Millimeter Products

These waveguide bandwidth detectors use silicon beam lead diodes on a planar stripline circuit to obtain an extremely rugged and compact device. Most millimeter wave broadband detectors have very poor VSWR due to the difficulty in obtaining a good wideband impedance match to the diode. To overcome this problem, these detectors utilize two diodes and an internal matched termination and 3 dB hybrid as shown below. This circuit allows a VSWR of 2.0 or better over a full waveguide bandwidth for most of these detectors. Detectors for waveguides WR-8 and smaller use a single zero bias GaAs diode. The high sensitivity zero bias GaAs diodes can also be special ordered for use at lower frequencies when highest sensitivity is required.

TH1775 - Shenzhen Chuangxin Instruments Co., Ltd.

TH1775 is a DC Bias Current Source (or DC Magnetization Current Source) used for inductance measurement of inductors and transformer windings with DC bias current. Except for constant current output, low additional error and wide frequency response range are important for bias current inductance measurement. High frequency LCR meter could be used, when the frequency response range is wide enough. MPU controlled auto current balance technology is adopted to realize AC+DC current overlap and constant current output from 0 to ±20A. Two TH1775 can be paralleled to supply a maximum current up to 40A.TH1775 permits high frequency measurement up to 1 MHz and can be directly controlled by TH2816A, TH2817A, TH2818 and TH2819. TH1773/TH1775 with its low additional error, wide frequency response range and sweep output function is widely used in DC biased inductance measurement. TH1775 also provides a perfect solution for magnetic material analysis.

Shunt Voltage References

-

Analog Devices Inc.

Analog Devices Inc.

Analog Devices offers a broad line of shunt precision voltage references that combine excellent accuracy and temperature stability with low noise and small packages. These devices operate in a manner that is functionally equivalent to a Zener diode. The bias current must be set higher than the sum of the maximum quiescent current of the voltage reference and the maximum expected load current. Since shunt voltage references are typically biased with a resistor, the voltage reference can operate on a wide range of input voltages.

Teledyne RF & Microwave

Teledyne RF & Microwave

Teledyne RF & Micrrowave designed the Five Channel Amplifier specifically for a custom space application. Each independent channel used dedicated RF Input/Output and DC bias connections. Each channel's RF performance was tailored differently to meet the application requirements. All components were manufactured and screened per MIL-PRF-38534, Class K. Additionally, to meet mission requirements The top assembly was also tested for RF and DC parameters during MIL-STD-202 thermal cycling and random vibration environments. This effort required disciplined development, manufacturing and program management efforts to meet challenging mechanical and RF engineering requirements.
