Shunt Voltage References
-
Analog Devices offers a broad line of shunt precision voltage references that combine excellent accuracy and temperature stability with low noise and small packages. These devices operate in a manner that is functionally equivalent to a Zener diode. The bias current must be set higher than the sum of the maximum quiescent current of the voltage reference and the maximum expected load current. Since shunt voltage references are typically biased with a resistor, the voltage reference can operate on a wide range of input voltages.

2-18GHz Instantaneous Frequency Measurement Unit
DR073
-
Teledyne Defence & Space’s Instantaneous Frequency Measurement (IFM) module, also known as a Digital Frequency Discriminator (DFD), offers high speed frequency measurement across the full operating bandwidth.The IFM measures the frequency of RF signal present at its input and presents a result at its output as digital data. The RF input signal is conditioned by an RF amplifier that provides sufficient drive for the frequency resolving circuits. The raw video from the resolvers is digitised and processed into the required output format. There is additional timing and control circuitry which initiates the measurement process and provides handshake data to the host system processor.
