The HP 8449B 1 to 26.5 GHz high-gain, low-noise preamplifier increases the sensitivity of any microwave spectrum analyzer, enabling you to detect and analyze very low-level signals in dramatically reduced measurement time. The improved sensitivity lets you widen bandwidths and measure low-level signals using much shorter sweep limes. Specifications. Frequency range: 1.0 - 26.5 GHz. Maximum safe input power: +20 dBm. Maximum dc input: +20 Vdc. Gain compression: < 1 dB for signals <= +7 dBm at the output (characteristic). Gain: > 26 dB (20-30° C); 30 dB (20-30° C) ; > 23 dB (0-55° C). Noise figure: < 8.5 dB (1.0 - 12.7 GHz), < 12.5 dB (12.7 - 22.0 GHz), < 14.5 dB (22.0 - 26.5 GHz). Third-order intercept: + 15 dBm at the output (characteristic). Second harmonic intercept: + 30 dBm at the output (characteristic). RF input/output: APC-3.5 (m) , 50-ohm (nominal). Reverse isolation: > 75 dB.
