The KH600 includes 50Ω resistors from each
input to ground (resulting in a differential input
impedance of 100Ω).
Description
The KH600 is the first amplifier to combine differential input
and output with a bandwidth of DC-1GHz at 2Vpp. The
inputs and outputs are 100Ω differential (50Ω single ended).
The KH600 operates from ±5V supplies and offers a fixed
gain of 14dB (5V/V).
The KH600 also offers optional supply current, differential
output offset voltage, and common mode offset voltage
adjustments.
The KH600 is constructed using Cadeka's in-house thin film
resistor/bipolar transistor technology. The KH600 is available
in a 12-pin TO-8 package.
