Avago announces 2 new high-linearity gain block amplifiers
Avago Technologies, a 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.
Additional AVT-55689 and AVT-54689 Product Features

U.S.Pricing and Availability
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.
Avago Unveils 120 Gigabit HD Embedded Parallel Optical Interconnect
New MiniPOD platform is said to offer industry’s first small-footprint modules with removable optical connector and pluggable electrical connector for 120 Gbps interconnect applications.
Avago Technologies has showcased a high- bandwidth, high-density parallel optic solution for short-range data and communication interconnect applications at the Super Computing 2010 conference.
The new 12-channel embedded MiniPOD parallel optics transmitter and receiver modules support lane rates of up to 10 Gigabits per second (Gbps) for an aggregate bandwidth of up to 120 Gbps. The small-footprint modules feature a low-cost, removable fiber cable connection and a pluggable electrical connection that provide flexible cable management at installation, simplifying design and lowering cost for switching and supercomputing applications.
The new MiniPOD optical modules incorporate Avago 850-nm Vertical-Cavity Surface Emitting Laser (VCSEL) technology, Avago PIN array technology, and Avago integrated laser driver and receiver IC technology, which combine to provide robust electrical and optical performance at these high data rates.
Using separate transmitter and receiver modules provides design flexibility and lowers the total
