LTC643x Gain Block RF/IF Amplifiers

Analog Devices Inc. LTC643x Amplifiers are RF/IF gain block amplifiers with a high linearity (OIP3), low associated noise, and low power distortion. The LTC643x amplifiers draw from a single 5V supply and consume as little as 93mA. The amplifiers operate with excellent linearity from frequencies below 100kHz to beyond 1000MHz. The LTC643x amplifiers are internally matched to 50Ω or 100Ω and provide a typical power gain of 15dB or 20dB. These fixed gain amplifiers offer on-chip bias and temperature compensation to maintain reliable performance when environmental changes occur. Analog Devices LTC643x's high linearity, low noise, and low power dissipation make these amplifiers well-suited for many signal-chain applications.
