IAM - 93516
High Linearity Integrated GaAs Mixer
Data Sheet
Description
Avago Technologies’ IAM-93516 is a high linearity GaAs FET
Mixer using 0.5um enhancement mode pHEMT technology.
This device houses in a 3x3 LPCC package. The IAM-93516
has a built-in LO buffer amplifier and an IF amplification
stage that serve as an ideal solution for reducing board
space and delivering excellent high IIP3, gain and isolation
with a low LO drive power. The device is designed with a
differential configuration to provide good noise immunity.
The LO port is 50 ohm matched and can be driven differ-
ential or single ended. An interstage match is introduced
between the mixer and amplifier stage to allow device
tuning at the desired RF and LO frequency. The interstage
match can be a simple low pass, high pass or intermedi-
ate frequency trap. The amplifier output port is 200 ohm
matched and fully differential. The simple matching at
the RF port provides for optimum input return loss, noise
figure and IIP3 performance.
The IAM-93516 is ideally suited for frequency down con-
version for base station radio card receiver, microwave link
receiver, MMDS, modulation and demodulation for receiver
and general purpose resistive FET mixer, which require high
linearity. All devices are 100% RF and DC tested.
Applications
• Frequency down converter for base station radio card,
microwave link transceiver, and MMDS
• Modulation and demodulation for receiver
• General purpose resistive FET mixer for other high
linearity applications

Notes:
5. Distribution data sample size is 510 samples taken from 3 different wafers lots. Future wafers allocated to this product may have nominal val-
ues anywhere between the upper and lower limits.
6. Measurements were made on a production test board, which represents a trade-off between optimal Gain, IIP3, NF, P1dB and isolation. Board
losses of 0.1dB at the RF input and IF amplifier output have been compensated. Balun loss of 0.57dB which was obtained from the Toko’s sup-
plied s-parameter file is also compensated. The total IF amplifier output loss is 0.67dB.
7. The device current is measured without LO signal. At LO=0dBm, the current reduces by around 6 to 7mA.
