Description

      The PE4125 is used widely, the following is its description. The PE4125 is a high linearity, passive Quad MOSFET mixer for GSM 800 & cellular Base station receivers and exhibits high dynamic range performance over a broad LO drive range up to 20 dBm. This mixer integrates passive matching networks to provide single-ended interfaces for the RF and LO ports, eliminating the need for external RF baluns or matching networks. The PE4125 is optimized for frequency down-conversion using high-side LO injection for GSM 800 & cellular base station applications, and is also suitable for use in up-conversion applications. The PE4125 is manufactured on Peregrine's UltraCMOS™ process, a patented variation of silicon-on-insulator (SOI) technology on a sapphire substrate, offering the performance of GaAs with the economy and integration of conventional CMOS.
      The PE4125 is a very good product. If you want to use it you must learn about it rightly. Here you can know that the PE4125 has five features. Please pay attention to them. The first feature of the PE4125 is that it is integrated, and single-ended RF & LO interfaces. The second feature of the PE4125 is that the high linearity is IIP3 > +32 dBm, 820 - 920 MHz (+17 dBm LO), the third is that the low conversion loss is 6.9 dB(+17 dBm LO). The next is that high isolation, which is that it is typical LO-IF at 43 dB,LO-RF at 31 dB. The last feature of the PE4124is that it is designed for low-side LO injection.
      The absolute maximum ratings of the PE4125 are those values listed as followings. Firstly, the storage temperature range from -65°C to  150 °C. The second absolute maximum rating is that the operating temperature range from-40 to 85 °C. The third absolute maximum rating is that LO input power is 20 dBm. The next absolute maximum rating is RF input power, which is12 dBm. The last absolute maximum rating is VESD ESD sensitive device, which is 250 V. Exceeding these values may cause permanent device damage. Functional operation should be restricted to the limits in the DC Electrical Specifications table.Exposure to absolute maximum ratings for extended periods may affect device reliability.
      There are also some notes of PE4125 you should know. The first is that an IF frequency of 70 MHz is a nominal frequency. The IF frequency can be specified by the user as long as the RF and LO frequencies are within the specified maximum and minimum. The second is that conversion loss includes loss of IF transformer (M/A COM ETC1-1-13, nominal loss 0.7dB at 70 MHz).
