LNF-PS3b is a compact power supply designed for LNF’s Low Noise Amplifiers. The drain
voltage is regulated and adjustable within a wide range, and the gate voltage is
automatically and continuously adjusted to give a set drain current. Vd and Id are displayed
on the LCD monitor screen for easy bias control. Vg can be monitored for trouble shooting
through the banana sockets on the front panel using a multimeter. Vd and Id are set by trim
potentiometers on the front panel. The LNF-PS3b is redesigned from ground up and features
new low noise electronic components for much improved performance compared to
previous models. There’s also a drain voltage sense function for situations where bias wire
resistance is significant. The display can be switched off for ultra-low noise operation. The
power supply is powered by LNF’s Power Block, LNF-PBA.
