Model D30NA30Z4 Surface Mount Attenuator 30 Watts, 30dB The D30NA30Z4 is a high performance Aluminum Nitride (AlN) chip attenuator intended as a cost competitive alternative to Beryllium Oxide (BeO). The attenuator is well suited to all cellular frequency bands such as; AMPS, GSM, DCS, PCS, PHS and UMTS. The high power handling makes the part ideal for inter-stage matching, directional couplers, and for use in isolators. The attenuator is also RoHS compliant! Features: • RoHS Compliant • 30 Watts • Low Cost • DC – 3.0GHz • AlN Ceramic • Non-Nichrome Resistive Element General Specifications Resistive Element Substrate Terminal Finish Operating Temperature Thick film AlN Ceramic Matte Tin over Nickel Barrier -55 to +200°C (see de rating chart) Tolerance is ±0.010”, unless otherwise specified. Designed to meet or exceed applicable portions of MIL-E-5400. All dimensions in inches.
