IMS Introduces 0-70dB 1Watt 1206 Attenuator

Portsmouth, Rhode Island, USA - International Manufacturing Services, Inc. (IMS), a leading manufacturer of high quality thick film components to the electronics industry, announces the introduction of its new IMA2391 surface mount thick film 1206 attenuator especially suited to RF/Microwave applications and communications-oriented circuitry.

The IMA2391 thick film attenuator is operational to 15GHz in a properly matched continuous 50 ohm system. It is available from 1 dB to 70 dB in 1dB increments with a tolerance as low as +/- 0.2dB. Input power handling is 1W (using proper thermal management techniques). The architecture is characterized by an alumina substrate with solderable input terminals on the top, and designed to be mounted to a single contiguous groundplane. Nominal Impedance is 50 ohms. 75 ohm or 100 ohm impedances are also available.

IMS' semi-custom series of passive thick film attenuators, low pass filters, dividers and power splitters were created specifically for applications where performance is the most critical parameter. These devices employ a proprietary core design that can be quickly and inexpensively adapted to individual circuit requirements, if necessary.

Since 1974, IMS has supplied the electronics manufacturing industry with highest quality thick and thin film chip resistors and chip attenuators. For more information, visit, or contact the company at 50 Schoolhouse Lane, Portsmouth, RI, 02871 USA, Tel. 401-683-9700. Fax 401-683-5571, e-mail:
