The PE4151 from pSemi is an UltraCMOS passive mixer with an integrated LO amplifier that operates from 136 to 520 MHz. This ultra-high linearity quad metal-oxide-semiconductor field-effect transistor (MOSFET) mixer is designed for use in upconversion and downconversion applications and is ideal for highly magnetic environments such as medical applications. It is available in a 3 x 3 mm, 10-lead MSOP package.
The LO amplifier allows for LO drive levels of less than 0 dBm to produce third-order intercept point (IIP3) values similar to a quad MOSFET array driven with a 15 dBm LO drive. The PE4151 operates with differential signals at the RF and IF ports while the LO port can be either differential or single-ended.
