Low Noise Pre-Amplifiers
-
Low Noise Pre-Amplifier and companion external low noise amplifier (LNA) are used to amplify low level microwave signals. The Pre-Amplifier contains an AC/DC power supply, internal low noise amplifier, and a bias tee to source a DC bias voltage on the RF input connector.To overcome cable loss between the test antenna and the Pre-Amplifier assembly, a remote low noise amplifier (LNA) is mounted directly onto the 10 GHz antenna. A bias tee inside the Pre-Amplifier chassis powers the remote LNA through the coax cable interconnecting the pre-amplifier and the 10 GHz test antenna.

External Pre-amplifiers
-
Although all Spectrum A/D cards have a very powerful input section with a highly configurable input amplifier and a variety of input ranges it is sometimes necessary to have additional external amplifiers if the signal to acquire has an extremely low level. Spectrum offers a range of perfectly matching external amplifiers to cover such cases. These powerful amplifiers have been rated using the Spectrum cards and offer best performance together with high amplification rates.The amplifiers are simply connected between the signal source and the Spectrum A/D card input and can be manually switched between different settings using small lever keys. All amplifiers allow the offset compensation by using an adjustable screw.

Preamplifiers
-
The primary function of a preamplifier is to extract the signal from the detector without significantly degrading the intrinsic signal-to noise ratio. Three basic types of preamplifiers are available: the current-sensitive preamplifier, the parasitic-capacitance preamplifier, and the charge-sensitive preamplifier. ORTEC manufactures a preamplifier to fit your detector, your application, and your budget.

Current Mirrors
-
Analog Devices current mirrors are precision, high dynamic range, wide variable supply parts used for optical power monitoring, voltage biasing with current monitoring, and voltage-to-current conversion. Our current mirrors can monitor current down to as little as 3 nA and as much as 3 mA, with a linearity of 1% or better. The current dynamic range is 120 dB or 6 decades of current range, while the overcurrent protection feature in our devices forces the input pin to ground to avoid part damage. Over temperature (–40°C to +85°C) and process, the dynamic range only suffers 10 dB at the lower end of the range.
