Filters
In order to minimize filter roll-off, we start with a quality, highly polished substrate and apply layers of metallization within tight tolerances. Our highly anisotropic ion beam etching process enables us to produce features down to 10 microns. Furthermore, the milling process yields a high consistency from circuit to circuit meaning that whether we produce 1 or 100,000 filters, each one will have consistent filter roll-off characteristics.

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.

Mid-Range Gas Filter Correlation CO Analyzer
Model T300M
Teledyne Advanced Pollution Instrumentation
The Model T300M CO analyzer measures low to mid ranges of carbon monoxide by comparing infrared energy absorbed by a sample to that absorbed by a reference gas according to the Beer-Lambert law. Using a Gas Filter Correlation Wheel, a high-energy IR light source is alternately passed through a CO filled chamber and a chamber with no CO present. The light path then travels through the sample cell, which has a folded path of 2.56 meters.
