PAM-0118 Preamplifier 20 MHz - 18 GHz This preamplifier has a broad frequency range and high gain, designed to match the double ridge guide horn antenna. An ideal solution for improving system sensitivity. larger image Frequency Range 20 MHz - 18 GHz Gain (typical) 38 dB Gain (minimum) 36 dB Noise Figure 2.5 dB Flatness /- 2.5 dB Maximum Power (dBm) @ 1 dB compression 9 dBm VSWR (typical) less than 1.7:1 Input Power 110/220 VAC regulated P/S output: 15 VDC 185 mA Connector: N(f) to N(f) Physical Dimensions: Height: 2.5%22 / 63mm Width: 3.75%22 / 95mm Length: 6.25%22 / 158mm Weight: 1.1 lbs. / 0.5 kg Features Frequency Range of 20 MHz to 18 GHz Low Noise, High Gain Individually Calibrated (gain calibration included) Low VSWR This preamplifier line is an excellent choice with a rugged design, no hassles with soldering your own power leads and they improve overall system sensitivity by at least 38 dB. All of A.H. Systems' Preamplifiers come with a 15-volt DC regulated power source. A low voltage indicator confidently allows you to power the amplifier with your own external 15-volt DC battery. This makes it a convenient choice for field measurements.
