Conexant Offers CX65100 Series Power Amplifier Modules

March 21, 2002 by Jeff Shepard

Conexant Systems Inc. (Newport Beach, CA) introduced a new family of power amplifier modules (PAMs) targeting current- and next-generation wireless infrastructure transmitter applications. Conexant's new CX65100 Series is designed to meet the performance, functionality and cost requirements of developing cellular and paging networks, personal communications systems, wireless local loop, digital cellular systems for every major standard, and mobile radio base stations operating up to 2,200MHz.

The new PAMs achieve high gain, output power and linearity over a wide range of frequencies. The series includes the CX65100-11 and CX65104-11, which operate from 700MHz to 1,000MHz, and feature typical radio frequency performance of 30dBm Pout, and efficiency over 39 percent. In addition, the CX65101-11, CX65102-11 and CX65105-11 each cover the 1,700MHz to 2,200MHz frequency range, with typical Pout up to 28.5dBm, 22dB to 24dB of gain, and efficiency from 24 to 30 percent. Conexant's CX65100 PAMs offer low noise, from 4dB to 6dB, and are designed for time division multiple access, advanced mobile phone service, global systems for mobile communications, code division multiple access, orthogonal frequency division multiplexing and other types of modulation.

The series includes internal, 50 ohm input/output impedance matching and internal active bias circuits for ease of design and low manufacturing costs. The CX65104-11 and CX65105-11 require a +5Vdc bias voltage, while the CX65100-11, CX65101-11 and CX65102-11 operate at +3.4Vdc. Each PAM is in an 8mm x 8mm, eight-pin, leadless chip carrier, surface-mount package. The CX65102-11 is sold in a 6mm x 6mm, six-pin leadless chip carrier, surface-mount package.

The CX65100 PAMs are available now and are priced at $4.21 in quantities of 10,000.
