PAM-1840

The AH Systems PAM-1840 is a wideband high-frequency preamplifier covering 18 GHz to 40 GHz, designed to overcome the attenuation challenges that arise at millimeter-wave frequencies. With a typical gain of 20 dB and a minimum of 15 dB, it improves overall system sensitivity at frequencies where signal levels can drop significantly, making it a practical solution for high-frequency EMC lab and field RFI measurements.

Key specifications include a noise figure of 4.5 dB, gain flatness of ±3.5 dB, a typical VSWR of less than 1.7:1, and an output power of +6 dBm at 1 dB compression. The unit uses 2.9mm female connectors at both ports, suited to reliable performance across the full 18–40 GHz range. Each unit is individually calibrated with a gain calibration certificate included.

The PAM-1840 is powered by a 100/220 VAC regulated supply outputting 15 VDC at 180 mA. A low voltage indicator enables operation from an external 15V DC battery for portable field use. Physical dimensions are 2.5" × 3.75" × 6.25" with a weight of 1.1 lbs (0.5 kg). It carries a three-year warranty and is backed by AH Systems' next-day delivery support.
