BRUSSELS — Jazz Semiconductor, a leader in Analog-Intensive Mixed-Signal (AIMS) foundry solutions and Hangzhou Sicomm RF Technology, Inc. ("Sicomm"), a company dedicated to the design of RF and mixed-signal chips and systems, have announced that Sicomm has developed a high gain and high efficiency power amplifier (PA) chip series, designated SRT3600/01/02/04.
The SRT3600 series of chips offers high performance in CW or FM signal amplification, especially for 400 MHz to 470 MHz band Walkie-Talkie applications. The devices are fabricated on Jazz Semiconductor's recently announced 0.18-micron Silicon Radio Platform using a high-power CMOS module ideally suited for highly integrated products that require higher breakdown voltages and high density CMOS.
The SRT3600 power amplifier chip series is targeted for applications including dual-mode Walkie-Talkies, such as Family Radio Service (FRS) and General Mobile Radio Service (GMRS), commercial and consumer systems, portable battery-powered equipment, and long distance remote control. Features of the devices include single 3.6-V to 6-V supply voltage, 400 MHz to 470 MHz operation frequency, 39-dB power gain, 36-dBm output power at 6 V, and 60 percent power added efficiency. Their output match is implemented on printed circuit board and can be easily adjusted to obtain optimum power and efficiency characteristics. The devices are packaged in small plastic QFN packages.
Sicomm utilized Jazz Semiconductor's 0.18-micron Silicon Radio Platform built upon the company's dual gate 1.8-/5.0-V 0.18-micron CMOS baseline process. The Silicon Radio Platform includes options such as the high-power CMOS module used in the design of the SRT3600 as well as high density MIM capacitors, resistors and thick power metal. It also offers an SOI option for integration of the antenna switch.
"We are pleased to partner with Sicomm in bringing to market innovative power amplifier products that take advantage of our Silicon Radio Platform technology," said Chuck Fox, vice president of sales and marketing, Jazz Semiconductor. "The Silicon Radio Platform is designed to enable silicon alternatives to more expensive GaAs front-end module components in markets that span all wireless interfaces, from Walkie-Talkies to cellular applications."
"Our SRT3600 power amplifier series is among the most innovative chipset Sicomm offers as a total system solution for Walkie-Talkie applications," said Zhongming Shi, chief executive officer, Sicomm. "Using Jazz's 0.18-μm Silicon Radio Platform, we achieved first silicon success and have been able to deliver high performance PA chips to our customers in a very timely manner with a high level of satisfaction."
