Two new linearity gain blocks from Avago operate in frequency band of DC to 6 GHz

Avago Technologies has released 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. The suggested applications include cellular and WiMAX wireless base stations, satellite and cable TV set-top boxes, military equipment.

The AVT-55689 and AVT-54689 gain blocks are made using compound semiconductor material such as Indium Gallium Phosphate (InGaP) Hetero-junction Bipolar Transistor (HBT) for delivering higher performance. 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:
--Built-in temperature compensated internal bias circuitry
--Uniformity in product specifications to minimize yield impact
--RoHS-Compliant and MSL-1 rated package: lead and halogen free
