Analog Devices Inc.

RF amplifier bias controllers generate a regulated drain voltage and actively adjusts the gate voltage of an external amplifier to achieve constant bias current. It can be used to bias any enhancement and depletion type amplifier operating in Class-A regime with drain voltages (VDRAIN) as specified. These devices achieve excellent bias stability over supply, temperature and process variations, and eliminates the required calibration procedures used to prevent RF performance degradation due to such variations.

J2130A - PICOTEST Corp.

When using the network analyzer to measure impedance, such as the capacitance and ESR or a capacitor, or the DCR of an inductor, etc., it is often necessary to provide a voltage bias to the device being tested. This is true of semiconductor junction capacitances, varactors, and some ceramic capacitors (especially X5R). In these cases the impedance is a function of the DC bias on the device. The Picotest DC bias injector (J2130A) is used for this purpose during impedance measurements.

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.

Four Channel Low-Noise DC Bias Card

PI-41702

Pulse Instruments

PI-41702 - Pulse Instruments

The PI-41702 is a four channel bipolar DC Bias supply that can provide an output current up to 100 mA per channel. The output voltage ranges from –8 V to +8 V, and this card has special filter circuitry to reduce the output noise for those applications that require a low noise bias output. Additionally there is a ‘D’ type connector that allows the introduction of laboratory type supplies to reduce the noise further. To change from using the internal power supplies to external power supplies requires repositioning jumpers. The PI-41702 also has voltage and current sense for remote measurement of the voltage and current levels.

Maury Microwave Corporation

MBT series - Maury Microwave Corporation

The MBT-series of bias tees is based on Maury's patented broadband capacitor (US Patent 9,614,267) which simultaneously enables the industry's widest bandwidth, lowest insertion loss and lowest return loss in a coaxial bias tee up to 18 GHz. In addition, its unique design makes it ideal for pulsed applications, including pulsed IV and pulsed load pull characterization, without distorting the voltage and current waveforms.
