The LNA 6900 is a low noise ampli? er with 25 dB of gain covering the nominal frequency range 9 kHz to 2 GHz and can be used up to 4 GHz. With its high gain and low noise ? gure, it will signi? cantly increase the sensitivity of virtually all spectrum analyzers and other RF measuring instruments. All measuring instruments have a ‘noise ? gure’, which is a measure of how good the instrument is at measuring low level signals, the lower this ? gure, the better, although the lowest signal level will still be governed by the measurement bandwidth. A typical spectrum analyzer may have a noise ? gure of 20 dB or more, whereas a typical receiver may have a noise ? gure of 10 dB. The preampli? er has a noise ? gure of typically 4 dB, signi? cantly enhancing the low level performance of such instruments, enabling signals that were previously masked by noise to be seen.The low noise ampli? er can be connected directly to the RF input (N) of the spectrum analyzer or EMI-receiver. If the LNA 6900 is used with the Teseq receiver SCR 35xx / SMR 45xx, the power supply is provided directly by the receiver via the cable LE 237. Alternatively the power supply unit PSU 6000 can be used.Frequency range: 9 kHz to 2 GHz (nominal range) 9 kHz to 4 GHz (utilizable range)Gain: typ. 25 dBGain ? atness: +0.5 / -3 dBRF-Input: N - female, 50 ?RF-Output: N - male, 50 ?VSWR (input): typ. 1.5 (above 20 kHz) Noise ? gure: typ. 4 dB1 dB-compression (output): >+12.5 dBm (119.5 dBμV)1 dB-compression (input): -12.5 dBm (94.5 dBμV)Intercept point IP3 (output): typ. +33 dBmDC-power supply: 11 to 15 V DC-current: approx. 112 mA DC-connector: ODU-female, plus on inner conductorsOperating temperature range: 0° to 40°CStorage temperature range: -20° to 60°CSize (W x D x H) (without connectors): 27 mm x 50 mm x 27 mmSize (W x D x H) (including connectors): 28 mm x 95 mm x 27 mmWeight: approx. 127 g
