Passive intermodulation analyzers

Summitek Instruments has upgraded the hardware design of its passive intermodulation analyzers, used to test radio-frequency components used in base stations. The new architecture includes an RF module for frequency generation and signal reception; a power-amplifier module for generating high-power signals; and a front-end module for combining two high-power signals into a single RF path. The analyzers operate in the 150 MHz to 3600 MHz band, according to the company.

Mobile computer

Socket Communications unveiled its new hand-held mobile computer, the Socket SoMo 650. The device has a touch screen, a Windows Mobile 5.0 operating system and Wi-Fi (802.11b/g) and Bluetooth technologies for wireless communications. It also offers a durable form factor capable of withstanding multiple drops from 1 meter onto vinyl-covered concrete, according to the company.

The SoMo 650 is the first in a family of hand-held computing products Socket will roll out in 2007 and is available through the company's distribution channels with a manufacture's suggested retail price of $648.

RFIC phased array receiver

The University of California, San Diego, and Newport Beach, Calif.-based Jazz Semiconductor have developed an 8-element RFIC phased array receiver covering the 6 GHz to 18 GHz frequency range. The SiGe Bi-CMOS chip replaces 16 gallium arsenide (GaAs) chips and consumes 20 times less power than traditional phased array implementations. It will be used for miniature and low-cost phased arrays — a group of antennas in which the relative phases of the respective signals feeding the antennas are varied so that the effective radiation pattern is reinforced in a desired direction and suppressed in undesired directions — for X- to Ku-Band applications.

The chip provides RF gain from 12 dB to 24 dB with a noise figure of 6 dB, and can be integrated directly with eight planar antennas on a standard printed circuit board.
