PE4152 Mixer in LO Bypass Mode

Peregrine Semiconductor’s PE4152 quad metal-oxide-semiconductor field-effect transistor (MOSFET) mixer supersedes the PE4150 by offering integrated local oscillator (LO) enable and LO bypass modes. Importantly, the PE4152 provides a one-chip solution to customers who previously would have had to use two separate designs to achieve optimum performance. The PE4152 mixer operates from 100 to 1000 MHz (RF) and 200 to 900 MHz (LO) and delivers high linearity and superior LO-to-RF and LO-to-IF isolation levels of the bypassed LO amplifier relative to the enabled mode. Additionally, LO bypass mode results in lower power consumption. In LO bypass mode, the PE4152 is designed for LO power levels up to +23 dBm and exhibits a typical conversion loss of 8 dB. The PE4152 mixer is ideal for applications such as land-mobile-radio (LMR), portable radio, mobile radio, cellular infrastructure and set-top box (STB)/CATV systems.
