For high linearity amplifiers Avago uses InGaP
Avago Technologies has two high-linearity gain block amplifiers that operate in frequency bands from DC to 6000MHz.
The AVT-55689 and AVT-54689 gain blocks are fabbed on an indium gallium phosphate (InGaP) hetero-junction bipolar transistor (HBT) process.
SAN JOSE, Calif. & SINGAPORE–(EON: Enhanced Online News)–Avago Technologies (Nasdaq:AVGO), a leading supplier of analog interface components for communications, industrial and consumer applications, today announced two new high-linearity gain block amplifiers. The AVT-55689 and AVT-54689 gain blocks feature low current consumption and robust electrostatic discharge (ESD) protection, and are housed in an industry standard SOT-89 package. The new devices operate in frequency bands from DC to 6000 MHz.
Their ease of use and extended broadband performance make them ideal for cellular and WiMAX wireless base stations, satellite and cable TV set-top boxes, military equipment and a variety of other wireless applications operating in this broad frequency range.
The AVT-55689 and AVT-54689 gain blocks leverage Indium Gallium Phosphate (InGaP) Hetero-junction Bipolar Transistor (HBT) process to achieve state-of-the-art reliability, temperature stability and performance consistency. The devices are each internally matched to 50 ohms, eliminating the need for additional radio frequency (RF) matching components. The cost-efficient devices’ broadband gain is also ideal for cellular infrastructure designs that require the same driver amplifier or gain block for different frequencies.
AVT-55689 and AVT-54689 Performance
At the typical operating condition of 5V and 83 mA, the AVT-55689 device delivers performance of 17.2 dB Gain, 33.0 dBm Output Third Order Intercept Point (OIP3), 19.4 dBm Output Power at 1 dB Gain Compression (P1dB) and 4.4 dB noise figure at 2000MHz.
At the typical operating condition of 5V and 60 mA, AVT-54689 delivers performance of 17.4 dB Gain, 30.0 dBm OIP3, 17.7 dBm P1dB and 4.0 dB noise figure at 2000 MHz.
