Page 12: Overview
1.1 Overview Overview The SA-430F5 is an ultra-low-noise differential amplifier realizing both an equivalent input noise voltage density of 0.35 nV/ Hz and a noise figure of 1.1 dB at 50 Ω. Furthermore, it has 200 times gain and a wide bandwidth (400 Hz to 110 MHz) property for low impedance signal source of 50 Ω. -
Page 13: Operating Principle
The gain of A1 is 133 times and that of A2 is 3 times, so the total gain is 400 times (52 dB). The output impedance of this product is 50 Ω, so the gain of this product is 46 dB (200 times) for a 50 Ω load. Figure 1-1 Block diagram SA-430F5... -
