A Broadband Hybrid Solid-state and TWT Amplifier

Development of a broadband microwave amplifier for testing in the 800 MHz to 18 GHz frequency range
Test applications that require microwave power from 1 to 18 GHz are usually addressed by two amplifiers, a solid-state unit to cover the low frequency range and a traveling-wave tube amplifier (TWTA) for the higher range. The input signal must be switched between the two amplifiers and, if there...

A Compact Monopulse Feed for Tracking Antennas

Introduction to the requirements for a compact monopulse feed for use in a Cassegrain antenna configuration
With the steady improvements in tracking radar technologies over the past twenty years, the diameter requirements for antennas has been reduced to match the improvements in transmitter power and receiver sensitivity. This has led to a need for shorter feeds for use in Cassegrain configurations. Antenna feeds have recently...

The Design of Bandpass Filters Considering Frequency Dependence of Inverters

In general, practical inverters have frequency-dependent impedance or admittance. The equivalent circuits of several widely used inverters are investigated, consisting of ideal inverters plus frequency-dependent real and/or immittance parts. One of the...
By using impedance or admittance inverters, microwave bandpass filters can be designed more conveniently with only one kind of resonator. Theoretically, the inverters have to be frequency independent. However, this is not true for practical cases. One of the most serious degradations in frequency response of a bandpass filter...
