Avago Technologies Introduces Quad PIN Diode Attenuators in Lead-Free SOT-25 Packages; Devices Specified for 300 kHz to 3 GHz Operation, with High Linearity, Wide Attenuation Range and Matched RF Performance.

SAN JOSE, Calif. -- Avago Technologies today introduced a series of pi-connected quad PIN (positive-intrinsic-negative) diodes in a lead-free, SOT-25 surface-mount package. These matched quads simplify the design and lower the costs of voltage-controlled diode pi attenuators operating over the 300 kHz to 3 GHz frequency range. The devices offer the combination of high linearity to minimize signal distortion, and a wide attenuation range to provide high dynamic range.

Avago's HSMP-3816 and HSMP-3866 pi-connected diode quads are intended primarily for applications in the wireless infrastructure, including base stations and repeaters, and cable and satellite television. They are also appropriate for other applications operating below 3 GHz calling for high linearity combined with a wide attenuation range performance. Because the four diodes are adjacent dice from the same wafer, they offer closely matched RF performance.

"These quad PIN diode attenuators broaden our product portfolio and give customers the high linearity and attenuation range they need for their demanding, next-generation wireless designs," said Steve Saw CY, worldwide product marketing manager for silicon diode/RFIC products in the Wireless Semiconductor Division at Avago Technologies. "They also save valuable board space and manufacturing cost."

With +1.2 V control voltage, at 1 GHz, the HSMP-3866 features +30 dBm IIP3 (third-order input intercept point), up to 36 dB attenuation, insertion loss of -3 dB and -18 dB return loss (all typical). With +5 V control voltage, at 1 GHz, the HSMP-3816 features +45 dBm IIP3, up to 38 dB attenuation, -3 dB insertion loss and -22 dB return loss (all typical). An application note and demonstration boards are available to help customers maximize the performance of voltage-controlled pi attenuators using these devices.

U.S. Pricing and Availability

The HSMP-3816 is priced at $0.60 each, and the HSMP-3866 at $0.56, both at a 40,000-unit level. They are available in bulk on 3,000-piece 7-inch tape and reel, and 10,000-piece 13-inch tape and reel. Samples and production quantities are available now from Avago Technologies' direct sales channel and worldwide distribution partners.
