Primer on Noise Parameters

RF designers often find themselves working on input power matching their circuits to a 50-Ohm signal source. The goal of this task is to develop a matching network that delivers most of the input power to the device. For that, the matching network is optimized such that the reflection coefficient presented by the network to the signal source is low (typically less than 10dB return loss) over the required frequency range.

C-SW00160

Upgraded cryogenic USB-control switch matrix

NoiseTech is proud to announce a new version of cryogenic USB-controlled dual SPDT switches (C-SW00160-S2). These will replace the original C-SW0160 switches and will provide much improved thermalization (i.e. thermal resistance between their internal circuitry and the cryostat cold plate is much reduced). The new switches incorporate an optional temperature sensor. The two SPDT switches […]

C-IG0160C Cryogenic impedance generator

Upgraded cryogenic impedance generator with more features!

NoiseTech is proud to announce a new version of cryogenic impedance generators (C-IG0160CT and C-IG00335CT). These will replace the original C-IG0160C products and will provide much improved thermalization. The new impedance generators incorporate a bias-T at their output for biasing DUTs. Other new features include optional: a temperature sensor and a cold attenuator or cold […]

C-IG00335C Cryogenic impedance generator

New frequency range

NoiseTech is proud to introduce impedance generators (benchtop and cryogenic) operating from 30MHz to 3.5GHz frequency range (p/n IC00335C and C-IG00335CT). These have the same feature as the original series of 100MHz to 6GHz units. NoiseTech is proud to announce a new version of cryogenic impedance generators (C-IG0160CT and C-IG00335CT). These will replace the original […]
