Sensirion SHT31-DIS-B Humidity and Temperature Sensor Breakout Board
SEN-37002-F
-
Breakout board for the Sensirion SHT31-DIS-F with a built-in permeable membrane filter. This sensor is an extremely accurate digital (I2C interface) temperature and humidity sensing device, with +/-0.2C temperature and +/-2% humidity accuracy typical. These specs far exceed the accuracy of ICs that came before it, including the HTU2x and SHT1x series, and improves upon the success of the SHT2x that came before it. In addition, the SHT31-DIS-B has a wide input voltage range of 2.4V-5.5V and includes temperature isolation and airflow cutouts as recommended for the optimal operation. Finally, in the case of environmental changes that could cause light condensation, the SHT31-DIS-B has a built-in heater to burn off any condensate.

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.

Active Filter
J2190A
-
The J2190A active filter presents a high impedance (approximately 150kOhms) minimizing the loading of the circuit being tested. The output impedance is 50 Ohms allowing low noise coaxial connections to all typical test equipment. The 0.1Hz-10Hz noise band is common for opamp measurements, voltage regulators and voltage references. Many application notes offer schematics of such a filter for test purposes. An engineer’s time is much too valuable to be spent building test equipment. We have created a 4th order high pass and 4th order low pass filter with an optimally flat response and 0dB gain. Additional filters can be cascaded for even sharper cutoff.
