Product Specification
PE4135
Product Description
The PE4135 is a high linearity passive Quad MOSFET Mixer
for GSM800 & Cellular Base Station Receivers, exhibiting high
dynamic range performance over a broad LO drive range of 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 PE4135 is optimized for frequency down-
conversion using low-side LO injection for GSM800 & Cellular
Base Station application, and is also suitable for up-conversion
applications.
The PE4135 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.

1. Test conditions unless otherwise noted: IF = 70 MHz, LO input drive = 17 dBm, RF input drive = 3 dBm.
2. 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.
3. Conversion Loss includes loss of IF transformer (M/A COM ETC1-1-13, nominal loss 0.7 dB at 70 MHz).

Ground connections for Mixer. Traces
should be physically short and connect
immediately to ground plane for best
performance. The exposed solder pad must
also be soldered to the ground plane for
best performance.

Absolute Maximum Ratings are those values
listed in the above table. 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.
Electrostatic Discharge (ESD) Precautions
When handling this UltraCMOS™ device, observe
the same precautions that you would use with
other ESD-sensitive devices. Although this device
contains circuitry to protect it from damage due to
ESD, precautions should be taken to avoid
exceeding the rating specified in Table 3.
Latch-Up Avoidance
Unlike conventional CMOS devices, UltraCMOS™
devices are immune to latch-up.
