15dB Gain Differential Amplifier Delivers up to +50dBm OIP3 Linearity and Low Noise from 100kHz to 1.4GHz
2017-05-10 | ReturnThe LTC6432-15’s high dynamic range and extended bandwidth to low frequencies broaden its usefulness and improve performance in a wide range of amplifier applications including high sample rate A/D converter drivers, cable network amplifiers, broadband signal source conditioning, radar receiver IF amplifiers, software defined radio, VHF/UHF broadcast radios and RF test instruments.
The LTC6432-15 differential inputs and outputs are internally 100Ω terminated. Its inputs are matched from 100kHz to 1.4GHz, with better than 10dB return loss over the full bandwidth. The output is also matched from 100kHz to 1GHz. The amplifier needs only DC blocking capacitors at its inputs and outputs, two chokes for proper biasing, plus one feedback capacitor per output to extend its excellent gain flatness to low frequencies.
The LTC6432-15 operates from a single 5V supply. It draws a nominal 166mA supply current. The device is specified for operation over a case temperature range from –40°C to 85°C. The LTC6432-15 is available in a 4mm x 4mm plastic QFN package in two grades: a B-grade with all typical parametric performance at $3.69 each in 1,000-piece quantities, and a higher performance A-grade with tested and guaranteed specifications at $6.44 each. Both are available immediately from stock. For more information, visit www.linear.com/product/LTC6432-15.
