Wideband Active Filters

Linear Technology's family of fixed and tunable filters operating up to 28MHz bandwidth support a wide range of wireless communications, signal conditioning and RFID applications. Single channel and dual channels are available. 

The LT6600-15 combines a fully differential amplifier with a 4th order 15MHz lowpass fi lter approximating a Chebyshev frequency response. Most differential amplifi ers require many precision external components to tailor gain and bandwidth. In contrast, with the LT6600-15, two external resistors program differential gain, and the fi lter’s 15MHz cutoff frequency and passband ripple are internally set. The LT6600-15 also provides the necessary level shifting to set its output common mode voltage to accommodate the reference voltage requirements of A to D converters.
