DETECTORS, VIDEO

SERIES PB, PT

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:

OUTLINE 1

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.
