Fremont, Calif., March 25, 2005, Microwave
Technology Inc., An IXYS Company, (NASDAQ:SYXI), announced that it released
two high linearity Power Amplifier products for the 802.11 WiFi and the
emerging 802.16 WiMax base station applications.
The first PA product is
WPS-495922-02. It
operates over 4.9 to 5.9GHz band with 11dB gain and 32dBm output power at
1dB compression point. Based on MwT’s proprietary high linearity MESFET
technology, the Power Amplifier achieves superior Error Vector Magnitude (EVM)
performance of 2.5% at 26dBm output power level
under WiMax test signal (256
carriers and 64 QAM with 2/3 coding factor). The EVM performance also
includes 1.6% of accumulated errors from the modulator and driver stages.
The adjacent channel power ratio, ACPR, is less than –40dBc at 25dBm average
output power and the third-order intercept point, IP3, is as high as 47dBm
at 22dBm output power per tone.
WPS-495922-02 is pre-matched to 50 Ohms for
easy cascade. The PA is biased at 7.5V drain voltage and about 600mA direct
current. The
WPS-495922-02 is packaged in MwT 02 package, a low cost surface
mount LLC package. The package is lead free and has a proprietary copper
alloy based pallet for good thermal conductivity.
The second released linear
Product Amplifier product is the
WPS‑2527LD5-98. It operates over 2.5 to
2.7GHz band with 10dB gain and 37dBm output power at 1dB compression point.
The LDMOS based PA achieves high efficiency of 40% and superior error vector
magnitude (EVM) performance of 2.5% at 33dBm output power level under WiMax
test signal (256 carriers and 64 QAM with 2/3 coding factor). The adjacent
channel power ratio, ACPR, is less than –40dBc at 33dBm average output power
and the third-order intercept point, IP3, is 50dBm at 33dBm output power per
tone. WPS‑2527LD5-98 is pre-matched to 50 Ohms with input and output load
impedance then greater 10 Ohms. The PA is biased with 26V of drain voltage
and 100mA of quiescent direct current.
WPS‑2527LD5-98 is packaged in an
industry standard metal flange package with excellent heat sinking
properties.
“ I am very excited about these new
Wireless Power Amplifier products, “ said Dr. Greg Zhou, GM of MwT, “These
new products leverage MwT high linearity device technology and excellent
engineering design capability, which allow us to address the important
802.11 WiFi and the emerging 802.16 WiMax infrastructure markets with
superior performing products with high reliability and competitive
pricing.” Samples of both
WPS-495922-02
and WPS‑2527LD5-98
and the corresponding evaluation boards are available now. Contact factory
