4. All unmarked terminals are ground.
General Notes:
1. The AEF-35A-500 is a constant impedance, voltage
controlled, PIN diode
π
network variable attenuator covering
,
10 to 1,000 MHz.
2. Careful design of thick film resistive pads and detailed
selection of suitable PIN diodes provide a wide operating
bandwidth and attenuation range. Units with closely controlled
phase shift are available as AFF-20A series.
3. Screened versions with extended reliability components are
available on request for Hi-Reliability and similar applications.
