InGaP HBTs from Avago Are Multitasking
The new broadband gain blocks deliver high linearity and low current consumption and are ideal for wide array of wireless communications and infrastructure applications.
Avago Technologies, a leading supplier of analog interface components for communications, industrial and consumer applications has revealed 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.
Additional AVT-55689 and AVT-54689 Product Features
• Input and output fully matched to 50 ohms
• Built-in temperature compensated internal bias circuitry
• Excellent uniformity in product specifications to minimize yield impact
• RoHS-Compliant and MSL-1 rated package: lead and halogen free
The AVT-55689 and AVT-54689 gain block amplifiers are priced starting from $0.63 and $0.59, respectively, in 10,000 unit volumes. Samples and production quantities are available now through the Avago direct sales channel and via worldwide distribution partners.
