GigOptix delivers E-band radio SiPs for point-to-point wireless back-haul

GigOptix Inc of San Jose, CA, USA (a fabless supplier of analog semiconductor and optical communications components for fiber-optic and wireless networks) has delivered engineering samples of E-band radio system in package (SiP) products - its first E-band transmitter and receiver in a small-form-factor surface-mount package - for point-to-point (PtP) wireless back-haul applications. 

The EXT7611-SSI/EXR7611-SSI and EXT8611-SSI/EXR8611-SSI are the system-in-package transceiver part numbers for 71-76GHz (low band) and 81-86GHz (high band) frequencies, respectively.

The transmitter SIP integrates a high-performance two-chip gallium arsenide (GaAs) solution with 20dB of available gain, OIP3 (output third-order intercept point) linearity of 29dBm and output power dynamic range control higher than 25dB. The transmitter SIP provides features such as envelope detector and power detector outputs for the best optimization of transmitter signal over noise and output levels.

The receiver SIP integrates a GaAs low-noise amplifier (LNA) and a silicon germanium (SiGe) BiCMOS down-converter, provides a typical noise figure of 5.5dB, excellent linearity and maximum available gain of 76dB over temperature. Baseband filters up to 750MHz and a baseband VGA (variable gain amplifier) are integrated on-chip, as optional features, and selected by a two-wire digital interface. Both the transmitter and receiver are designed to meet both FCC and ETSI requirements.

"This is the first transceiver package product of our roadmap to support the continue demand of higher data-rate in wireless applications," says chief technology officer Andrea Betti-Berutto. "The experience gathered by our team in development of the E-band transceiver is fundamental for GigOptix's participation in the upcoming 5G market," he adds.

GigOptix says that the E-band radio market is entering its maturity stage, with significant volume deployment, and is on the way to becoming one of the most deployed bands for wireless back-hauling of hundreds of thousands of radios for 2016. The upcoming 5G market is expected to dramatically increase the demand for millimetre-wave radios for back-haul, front-haul, and access.
