Active mixer meets 3G basestation demands

A new active mixer is designed to meet the critical performance requirements of 3G basestation radio cards and other microwave radio link applications.

Agilent Technologies has introduced a high-linearity, low-LO (local oscillator) power E-pHEMT (enhancement mode pseudomorphic high electron mobility transistor) MMIC (microwave monolithic integrated circuit) active mixer designed to meet the critical performance requirements of BTS (base transceiver station) 3G basestation radio cards and other point-to-point and point-to-multipoint microwave radio link applications.

The Agilent IAM-93516 high-linearity mixer is a new addition to Agilent's portfolio of mixers.

It combines high linearity with the industry's lowest LO drive requirement, low power consumption and broad operating frequency range.

It operates with RF and LO frequency inputs from 400 to 3000MHz and an IF output extending from 70 to 300MHz.

The IAM-93516 operates from a single 5V DC supply, consuming only 110mA typical.

It provides greater than +23dBm third-order input intercept point (IIP3), +19.3dBm linear power output (P1dB), 9dB conversion gain and 11.6dB noise figure (all typical).

LO-to-IF, LO-to-RF and RF-to-IF isolation are each greater than 20dB.

In a typical application (1.91GHz input frequency, 1.7GHz local oscillator and output of 210MHz), the mixer can handle an RF input as high as +10dBm without distortion, with a LO power input of only 0dBm.

The IAM-93516 is supplied in a 3.0 x 3.0 x 0.75mm lead-free and halogen-free 16-pin LPCC (leadless plastic chip carrier) 16L-LPCC3x3 package.

The LO port is matched to 50ohm and can be driven differentially or single-ended; the IF port is matched to 200ohm and is fully differential.

The RF port requires an external matching network for optimum input return loss and third-order intercept point (IP3) performance.

The IAM-93516 MMIC mixer is available packaged in bulk and in tape-and-reel on 7 and 13in reels.

Samples and production quantities are available now through Agilent's direct sales channel and worldwide distribution partners.
