A high speed, internally 50 Ohm matched, LO amplifier drives a double-balanced mixer core, allowing the use of a low power, single-ended LO source. An RF output transformer is integrated, thus eliminating the need for external matching components at the RF output, while reducing system cost, component count, board area and system-level variations. The IF port can be easily matched to a broad range of frequencies for use in many different applications.The LT5519 mixer delivers +17.1dBm typical input 3rd order intercept point at 1GHz with IF input signal levels of –10dBm. The input 1dB compression point is typically +5.5dBm. The IC requires only a single 5V supply.
