Microwave RF articlesGian I7SWX has spotted articles on a 144 MHz oscillator and PIN Attenuators on the Microwave & RF website. The April 2008 issue of Microwave & RF April 2008 has two interesting articles both of which are available on the web. (1) Large-Signal Approach Yields Low-Noise VHF/UHF Oscillators In contrast to traditional small-signal approaches, the use of large-signal, time-domain design techniques helps deliver low-noise grounded-base oscillators for VHF/UHF applications. Part 1 of this three-part article series explores the use of large-signal design techniques for a grounded-base 144-MHz oscillator.
Some simple techniques, such as the addition of a ferrite bead, can be used to reduce the minimum attenuation of a PIN diode attenuation for broadband, high-frequency applications.
