DESCRIPTION
The Series A150 ultraminiature Attenuator Relays are designed for
attenuating RF signals in 50-ohm systems over a frequency range from DC
to 3 GHz. Their low profile and small grid spacing makes them ideal for use
when packaging density is a prime consideration. The A150 relays eliminate
the need for additional external resistors.
SCHEMATIC DIAGRAM
3
These single section, switchable attenuator relays have internal matched thin
film attenuator pads in “L,” “T” or “Pi” configurations, as applicable. Relays are
available in fixed increments of 1, 2, 3, 4, 5, 6, 8, 10, 16 and 20 dB, which
5
can used singly or in combination to achieve the attenuation levels desired.
