Sirenza Microdevices, a leading designer and supplier of high-performance radio frequency (RF) components for communications equipment manufacturers, today expanded its SPA Series of linear power amplifier radio frequency integrated circuits (RFICs) with the addition of two new high-gain models. The SPA-2118 and SPA-2318 offer cellular, PCS and 3G equipment designers 32 dB of gain at 900 MHz and 23 dB of gain at 1.9 and 2.1 GHz, along with exceptional linearity previously unavailable in a single integrated circuit.
"These highly efficient, ultra-linear power amplifiers significantly strengthen our RFIC product portfolio for infrastructure-equipment manufacturers of next-generation wireless networks," according to Norm Hildreth, SMDI's vice president of wireless products. "Only SMDI offers in IC form the combination of gain, power and linearity available with the newly expanded SPA Series."
These gallium-arsenide (GaAs) heterojunction-bipolar-transistor (HBT) devices cover the 850 MHz, 1950 MHz and 2150 MHz frequency bands and perform as excellent driver amplifiers for wireless infrastructure equipment. Housed in standard surface-mount SOIC-8 plastic packages with backside metallization, the amplifiers are fabricated using state-of-the-art, high-performance GaAs semiconductor process technology.
"Our SPA amplifiers are powered with a single +5V supply voltage with an on-chip active bias circuit providing consistent performance over temperature," according to Greg Baker, SMDI's vice president of engineering. "These devices offer typical third-order intercept points of +47 to +48 dBm, IS-95 channel power of +23 to +24 dBm and W-CDMA (10.5 dB peak-to-average modulation, 64 DPCH + overhead channels) channel power of +21.5 dBm at -45 dBc adjacent channel power (ACP)."
Baker goes on to state, "SMDI performs 100-percent production testing on these parts for ACP, using digital-modulation waveforms representative of typical customers' applications."
The units are priced at $9.90 each in quantities of 50,000.
