Low-pass filter achieves high rejection up to 20 GHz
Jan 1, 2005
Implementing a 21-section cascaded Butterworth filter in its proprietary low-temperature, co-fired ceramic technology and combining it with a novel...
Specifying a quartz crystal for a VCXO
Aug 1, 2004
By Ramon M. Cerda A popular application for the voltage-controlled crystal oscillator is the forming
of a phase-locked loop. Designing the VCXO for this application requires a
‘pullable’ quartz crystal....
Combline filter design simplified
Jan 1, 2004
By Anurag Bhargava The range of filters that can be used in 200 MHz to 1 GHz band is limited, and this range becomes even narrower if a sharp rejection profile is needed....
