Harris Develops Highly Integrated 2.4 GHz Power Amplifier and Detector
Contributes to 50 percent reduction in power consumption for the PRISM® II Chip Set
SAN JOSE, CA, Wireless Symposium ‘99, February 23, 1999 – Harris Semiconductor has developed a highly-integrated RF power amplifier using advanced silicon germanium (SiGe) technology. The SiGe process allows the HFA3983 Power Amplifier and Detector to deliver performance while greatly reducing power consumption. The HFA3983 is one four chips that comprise Harris’ next generation PRISM II WLAN chip set, also announced today.
SAN JOSE, CA, Wireless Symposium 99, February 23, 1999 Harris Semiconductor has developed a highly-integrated RF power amplifier using advanced silicon germanium (SiGe) technology. The SiGe process allows the HFA3983 Power Amplifier and Detector to deliver performance while greatly reducing power consumption. The HFA3983 is one four chips that comprise Harris next generation PRISM II WLAN chip set, also announced today.
The HFA3983 is a 2.4 GHz monolithic power amplifier designed to operate in the unlicensed Industrial, Scientific and Medical (ISM) band. The device features two low-voltage single supply stages, delivering a minimum of +20.6 dBm of power at the 1dB compression point. The resulting solution effectively delivers a 50 percent reduction in power consumption over Harris first-generation PRISM WLAN Chip Set.
SiGe-based chips deliver a cutting-edge complement to Harris CMOS and BiCMOS technology due to their ability to provide greater design performance and flexibility. The SiGe process employs deep trench isolation, a noise-reduction methodology enabling designers to increase integration levels by placing functional blocks closer together on a single silicon die.
The HFA3983 is well-suited for a variety of wireless applications including wireless local area networks (WLANs), PCMCIA wireless transceivers, ISM systems including automatic level control (ALC) and TDMA packet protocol radios.
The device also includes a 2.4GHz power detector with 15dB of dynamic range and ±1dB of accuracy. When used in conjunction with an external power sampler coupling device, an accurate ALC function can be implemented.
Packaging, Pricing, Availability
The HFA3983 is housed in a 28-lead exposed paddle TSSOP package suitable for PCMCIA board applications. Samples of the HFA3983 will be available in May. Pricing in 10K quantities is $3.59.
