Teledyne Relays Announces Series A150 Ultraminiature Attenuator Relays

HAWTHORNE, California (April 25, 2005) - Teledyne Relays' Series A150 ultraminiature attenuator relays are designed for attenuating RF signals in 50-ohm systems over a frequency range from DC to 3 GHz.

The low profile and small grid spacing of the A150 relays makes them ideal for use when packaging density is a prime consideration, according to Antonio Gallegos, product-marketing engineer.

The A150 relays eliminate the need for additional external resistors. These single section, switchable devices 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 can used singly or in combination to achieve the attenuation levels desired.

The A150 relays features a unique uniframe motor design that provides high magnetic efficiency and mechanical rigidity. Gold-plated, precious metal contacts provide excellent intermodulation performance. The relays provide high isolation between control and signal path and are highly resistant to electrostatic discharge.

The A150 hermetic canister measures .49 x .375 x .28 inch (12.45 x 9.53 x 7.11 mm) and weighs .11 ounce (3.2g). Leads measure a minimum of 0.7 inch (17.78 mm).

The A150 is priced at $62.60 each in quantities of 500 units. Lead time for delivery is stock to 12 weeks weeks.
