Anyone who has to reduce the amplitudes of RF signals in a controlled manner needs an attenuator. Linearly adjustable attenuation networks using special PIN diodes are available for this, but they ...

This is a PIN diode based RF signal attenuator circuit operates with 1MHz – 500MHz input. PIN diodes are one of the most common parts used in RF applications generally as switches in transmitter and ...

In the RF world, attenuators are a useful test and measurement tool. Variable units that can apply different levels of attenuation in discrete steps are even better. [DuWayne] made a 63 dB step ...

These advanced attenuators are intended to optimise RF signal control in a wide range of applications. Designed to meet the demands of modern RF systems, the RF fixed attenuators offer improved levels ...

[Kerry Wong] comes across the coolest hardware, and always manages to do something interesting with it. His widget du jour is an old demo board for a digital RF attenuator chip, which can pad a signal ...

Pasternack has launched a new line of 10-, 25-, 50-, and 100-W RF attenuators with operating frequencies of up to 18 GHz, depending on the configuration. The company provides 31 high-power, fixed ...

Smiths Interconnect has announced 500mW surface-mount fixed attenuators that cover dc – 20GHz. Called TT9 SMT, the series is aimed at the defence market and “has undergone significant qualification ...

Filtering switches and bandpass filter design constitute a crucial intersection in the development of modern radio frequency (RF) front-end architectures. Recent advances have concentrated on ...
