Avago Technologies Announces New High Performance Broad Band InGaP HBT Gain Blocks

March 24, 2010 - PRLog -- Avago Technologies , a leading supplier of analog interface components for communications, industrial and consumer applications, today announced two new economical, easy to use general purpose InGaP Hetero-Junction Bipolar Transistor (HBT) MMIC gain block amplifiers for use in a variety of wireless applications.  Avago’s AVT-51663/53663 gain blocks, which operate within the DC to 6000MHz frequency band, can be used as either a broadband gain block or driver amplifier.  These gain blocks target designers of cellular infrastructure applications, but can be also be used in a variety of other wireless applications such as Base Stations, WiMAX, WLAN, CATV, Satellite TV and set-top boxes.

Avago’s AVT-51663/53663 gain block amplifiers, which are internally matched to 50-Ohms, were designed in Darlington configuration housed in an industry standard six-lead SOT-363 surface mount plastic package.  The Darlington feedback structure provides inherent broad bandwidth performance resulting in a useful operating frequency range of up to 6 GHz making the AVT-51663/53663 ideal for small-signal gain cascades or IF amplification.  Moreover, these new gain blocks feature easy installation and only require DC blocking capacitors, RF choke, biasing resistors and bypass capacitors for operation.  Additionally, no additional RF matching components are required to achieve broadband performance.

These new gain block amplifiers were developed using advanced InGaP HBT technology that offers state-of-the-art reliability, temperature stability and consistent performance.  At a typical operating condition of 5V and 37mA, the AVT-51663 delivers performance of 19.0dB gain, 24dBm Output Third Order Intercept Point (OIP3) and 12.5dBm Output Power at 1dB Gain Compression (P1dBm) and 3.2dBm noise figure at 2000MHz.  The AVT-53663 operates at 5V and 48mA to deliver a performance of 19.5dB Gain, 5dBm OIP3, 15dBm P1dB and 3.2dB noise figure at 2000MHz.
