RF Attenuators, Limiters and
Phase Shifters
Corry Micronics offers a line of 4 bit through 6 bit RF
digital attenuators. The digital attenuators are designed using switched bit pin
diodes. The attenuators require +/-5volt power supply and feature TTL compatible
control logic. Corry Micronics also offers a high REL option that includes
screen to the MIL-STD-883.
Corry Micronics’ voltage variable attenuators are current
controlled for high performance, compact design and are very cost efficient. For
the cost conscious buyer we offer the reflective style of voltage variable
attenuators. For those designs where any stray reflections would cause system
performance degradation we offer the non-reflective voltage variable
attenuators. Our attenuators are designed with a wide range of attenuation from
2db to 50dB in the reflective and 30dB in the non-reflective attenuator.
We leveraged our pin diode design expertise into our line
of Pin diode limiters. Limiters are used to protect sensitive active components
such as low noise amplifiers (LNA) or transmitter receiver front ends. Limiters
reduce the amount of power that these sensitive circuits receive. Our limiters
are designed to handle up to 100Watts of peak power.
We also custom design microwave phase shifters. These phase
shifters are available up to frequencies of 8 GHz and designed with 5 bit
resolution.
