P1-70 Series

Element, Ultra-low-noise FET Preamp. The P1-70 series features 1, 2, 3, and 5 mm diameter standard detector element sizes (respectively, P1-71, P1-72, P1-73, and P1-75) and incorporates a specially selected low-leakage current hybrid FET circuit. Because it uses a (3*1011) -ohm load/feedback resistor, this series offers superlative narrow-band, low-NEP performance.
