Juno modules are ideal for use in industrial devices as well as consumer products including wireless PC peripherals, video game controllers, and remote controls.
"SiGe Semiconductor's RF power amplification device is ideal for our WirelessUSB modules", said Mark Morrissey, Unigen Corp's Director of Business Development.
"The integration of the RF front-end circuitry, as well as the ability to seamlessly connect the device to Cypress' WirelessUSB radio simplified the design of our modules".
"The RF front-end also meets our specifications for reliability and transmission range, ensuring that products based on our Juno modules will support the high performance expectations of consumer electronics".
The SE2526A is based on SiGe Semiconductor's proven high-performance 802.11b/g power amplifier, able to achieve power output of +18dBm with an error vector magnitude (EVM) of 2.5% while operating in 802.11g mode.
In 802.11b mode, the SE2526A delivers +20dBm output power with an adjacent channel power ratio (ACPR) of less than -37dBc.
With industry-leading EVM, ACPR and harmonic performance, the RF front end enables wireless connections with high data throughput and long transmission range.
"The SE2526 RF front-end nicely complements our WirelessUSB radio technology".
"WirelessUSB employs Cypress' patent-pending interference avoidance technology, which enables robust performance and high signal integrity when operating in electrically 'noisy' environments".
"This, combined with the high output power of SiGe's RF front-end, enables reliable wireless connectivity over longer distances", said Rich Kapusta, Director of Marketing for the Wireless Business Unit in Cypress' Personal Communications Division.
"This is a significant win for SiGe Semiconductor that underscores our success in capturing market share with our WLAN power amplifiers and RF front-end solutions", said Alistair Manley, Senior Director of Marketing, SiGe Semiconductor.
"Unigen is among the leading companies delivering Wi-Fi modules to consumer device manufacturers".
"Our collaboration with Unigen and Cypress ensures performance that will provide consumers with an optimal wireless experience".
