Broadband programmable gain amplifier

14 July 2004 Analogue, Mixed Signal, LSI Products & Solutions

A new 850 MHz programmable gain, broadband amplifier from Linear Technology is claimed to have the best distortion characteristics of any amplifier in its class. The LT5514 exhibits an output third-order intercept (OIP3) of 49 dBm at 70 MHz, and has 2nd and 3rd order distortion products lower than -87 dBc, while delivering 2 V peak-to-peak output into a 200 Ω load. Its combination of low noise and high spurious-free output capability makes it a highly suitable driver for 12- and 14-bit, 65 Msps or faster A/D converters in high performance communication systems. The device's variable gain is adjusted by means of an on-chip, digitally controlled attenuator in combination with a fixed gain amplifier. At 50 Ω loads, the amplifier output can swing more than 3 Vp-p. As an amplifier, the LT5514 has a gain flatness of ±1dB over a 450 MHz bandwidth. It also introduces very little group delay, reducing phase distortion over a wide operating frequency.
