OCTAVE AND MULTI-OCTAVE
DETECTORS, VIDEO
0.2-18 GHz
GENERAL INFORMATION
Series PB and PT miniature Detectors achieve the input impedance
match without the use of resistive elements, which assures excellent sen-
sitivity. This unique design also results in low VSWR and low video ripple.
The units are supplied with either Schottky diodes (PT Series) or back
diodes (PB Series).

Notes:
1. Models with prefix PB use either zero bias, Schottky (back) diodes and
require no bias. Models with prefix PT use Schottky diodes and require 20
to 60 microamps bias.
2. Diodes are replaceable.
3. All units have DC returns.
4. Output voltages are negative.
5. Fig. 1 shows the relationship of tangential sensitivity versus video band-
width.
6. Fig. 2 illustrates the output voltage versus input power.
