VCO Test Methods

VCO Test Methods

Well regulated power supplies are recommended for tuning and VCO supplies. Bias tee's in the DC and tuning voltage lines help reduce the power supply noise. This article will cover information on
An Introduction to Filters

An Introduction to Filters

In the operation of electronic systems and circuits, the basic function of a filter is to selectively pass, by frequency, desired signals and to suppress undesired signals. The amount of ...
Band-pass Filters with Linear Phase Response

Band-pass Filters with Linear Phase Response

Filters with linear phase response are desirable, due to their flat group delay, in many applications, for example in image processing and digital data transmission. Such filters maximally ...
Super Wide-band RF Choke

Super Wide-band RF Choke

Use of heterojunction bipolar transistor technology has resulted in development of super wide-band monolithic microwave amplifiers such as Mini-Circuits ERA series. These amplifiers cover a ...
High Power Limiter Modules

High Power Limiter Modules

In many applications, front end filtering is used to protect the receiver from unwanted high-power signals, but even with this reinforcement, high-power signals may still be present. A limiter ...
Characterizing and Minimizing VCO Phase Noise

Characterizing and Minimizing VCO Phase Noise

The term phase noise is widely used for describing short term random frequency fluctuations of a signal. Frequency stability is a measure of the degree to which an oscillator maintains the same ...
