RELAY TYPE

DESCRIPTION

The A150 series 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 eliminate the need for additional external

resistors.

These single section, switchable attenuator relays have internal

matched thin film attenuator pads in “L”, “T” or “Pi” config-

urations, as applicable. Relays are available in fixed increments

of 1, 2, 3, 4, 5, 6, 8, 10, 16, and 20 dB which can used singly or

in combination to achieve the attenuation levels desired.

The A150 attenuator relay features:

• Unique uni-frame motor design which provides high

• Minimum mass components and welded

• Advanced cleaning techniques which assures

• Gold plated, precious metal contacts which

• Flat amplitude vs. frequency response.

• High isolation between control and signal path.

• Stable attenuation vs. temperature.

• Excellent phase linearity.

• Highly resistant to ESD.
