1GHz Ultra-Miniature Frequency Discriminators
Centre Frequency 1 GHz
Frequency Accuracy <5%
Linear Bandwidth >50%
Power Dissipation from 0.5W
The Pascall Ultra-Miniature series of Frequency Discriminators provide
broadband performance and superb linearity over a wide temperature
range.
The UMDLD range of discriminators are robustly constructed in
lightweight aluminium alloy housings and are designed to withstand
harsh mechanical environments.
This range is specified for operation over a case temperature range
maximum of -45ºC to +85ºC.
The standard supply voltage is +/- 5 Volts and options are available
for +/-12 and +/-15 Volts. The +/-5 Volt unit has a power dissipation
of less than 0.5 Watts. This offers distinct advantages in thermal
stability making it the ideal choice for compact airborne equipment
designs where low power dissipation is vital to maintain high reliability
and performance.
Pascall have a large range of alternative discriminators covering centre
frequencies from 10 MHz to 1 GHz and are also able to design models
to meet customers' specific requirements.
