Conexant launches new PA modules
"Wireless base station manufacturers are continually challenged by the increasing demand on their networks and insist on stringent performance requirements for next-generation base stations, mobile radios and wireless local loop systems," said Mohy Abdelgany, vice president of Conexant s RF subsystems business unit. "In order to meet their concerns, we ve leveraged our industry-leading GaAs HBT process technology to introduce a new family of medium-power, wideband, internally-matched power amplifier modules that enable system-cost reduction while at the same time meet next-generation performance requirements."
Technical Details
Conexant s new continuous wave wideband linear MMIC PAMs achieve high gain, output power (Pout) and linearity over a wide range of frequencies. The series includes the CX65100-11 and CX65104-11 which operate from 700 to 1000 MHz, and feature typical RF performance of 30 dBm Pout, up to 29.5 dB of gain, third order output intercept point (OIP3) up to 40 dBm and efficiency over 39%. In addition, the CX65101-11, CX65102-11 and CX65105-11 each cover the 1700 to 2200 MHz frequency range, with typical Pout up to 28.5 dBm, 22 to 24 dB of gain, up to 40 dBm OIP3, and efficiency from 24 to 30 percent. Conexant s CX65100 PAMs offer low noise figures, from 4 to 6 dB, and are designed for time division multiple access (TDMA), advanced mobile phone service (AMPS), global system for mobile communication (GSM), code division multiple access (CDMA), orthogonal frequency division multiplexing (OFDM) and other types of modulation.
Based on Conexant s leading AlGaAs/GaAs HBT technology, 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 +5 V DC bias voltage, while the CX65100-11, CX65101-11 and CX65102-11 operate at +3.4 VDC. Each PAM is in an 8x8 mm, 8-pin, leadless chip carrier (LCC), surface mount (SMT) package. The CX65102-11 is sold in a 6x6 mm, 6-pin LCC, SMT package.
Price and Availability
Conexant s CX65100 PAMs are available now and are priced at $4.21 in quantities of 10,000.
