Preamplifiers
LNA Series
-
Low noise amplifier with 12.5 dB of gain covering the nominal frequency range 1 MHz to 3 GHz and can be used in the range from 200 kHz to 4 GHz. With its high gain and low noise figure, it will significantly increase the sensitivity of virtually all spectrum analyzers and other RF measuring instruments. All measuring instruments have a 'noise figure', which is a measure of how good the instrument is at measuring low level signals, the lower this figure, the better, although the lowest signal level will still be governed by the measurement bandwidth. A typical spectrum analyzer may have a noise figure of 20 dB or more, whereas a typical receiver may have a noise figure of 10 dB. The preamplifier has a noise figure of typically 4 dB, significantly enhancing the low level performance of such instruments, enabling signals that were previously masked by noise to be seen.

Current Sensing
-
voltage-output, current-sensing amplifier family that integrates an internal shunt resistor to enable high-accuracy current measurements at common-mode voltages that can vary from 0 V to 36 V, independent of the supply voltage. The device is a bidirectional, low- or high-side current-shunt monitor that allows an external reference to be used to measure current flowing in both directions through the internal current-sensing resistor sensor. The integration of the precision current-sensing resistor provides calibration equivalent measurement accuracy with ultra-low temperature drift performance and ensures an optimized Kelvin layout for the sensing resistor is always obtained.

RX Pre-Amplifier System
RAM-34
-
The RAM-34 is a complete pre-amplifier system designed primarily for the low bands 160M thru 40M. It has inputs for four receive antennas and internal 3-pole bandpass filters for 160M, 80M and 40M. In addition to the pre-amplifier, it has a step attenuator that togetherwith the amplifier stage provides gains from -20 dB to +20 dB in 5 dB steps. This allows equalizing the signal levels between the antenna inputs. Gain settings are memorized for each antenna on each band. Different types of receive antennas have different signal levels and the gain memories eliminate the need to adjust the receiver or pre-amplifier when switching between the antennas.
