LTC6430 IC Amplifier Driver

Linear Technology's 15 dB, RF/IF amplifier achieves 50 dBm OIP3

Image of Linear Technology's LTC6430 IC Amplifier DriverLinear Technology's LTC6430-15 15 dB amplifier achieves high dynamic range in a 100 Ω differential environment from 20 MHz to over 1 GHz. Two performance grades are available. At 240 MHz, the A-grade OIP3 is typically 50 dBm, fully tested, and guaranteed to a minimum of 47 dBm. Its noise figure is 3 dB, which corresponds to an input-referred amplifier noise of 1 nV/√Hz. DC power consumption is 800 mW. This combination of low noise and low distortion provides wide dynamic range needed for high performance intermediate frequency communications and CATV applications.

The LTC6430-15 is easy to use, unconditionally stable, and the input and output are internally matched to 100 Ω differential. With greater than 2.75 VP-P linear output swing, it is well-suited for driving high speed, high performance ADCs. Two 1:2 baluns, DC blocking capacitors, and RF bias chokes achieve a wideband 50 Ω balanced amplifier in communications applications. With two 1:1.33 baluns, the LTC6430-15 can be used as a high fidelity 75 Ω CATV amplifier. The LTC6430-15 is available in a 4 mm x 4 mm QFN-24 package with exposed pad for best thermal performance and low inductance.
