Getting high output power
and excellent linearity in a
millimeter-wave amplifier is no
easy trick. But Avago has done it
with its AMMC/P-6333 (see the
figure). This high-performance
driver amplifier offers high gain
and power with excellent input
and output return losses. It also
targets the need for broadband
and eliminates the need for a
negative voltage. Primary applications
include wireless communication
infrastructure, point-to-point radios, very small
aperture terminals (VSATs), and fiber to the home (FTTH).
The AMMC/P-6333 millimeter-wave monolithic IC
(MMIC) is made using Avago’s unique 0.25-µm enhancement
mode pHEMT technology. It works over the 18- to 33-GHz
band and delivers a high gain of 20 dB and a P1dB of 23 dBm.
The third-order intercept point is 30 dBm. The input and output
matching networks are for 50 O. The device is available in a
5- by 5-mm surface-mount package or as a bare die. It operates
from a single 5-V supply with a current drain of 220 mA.
Pricing for the AMMC-6333 die begins at $13.20 in 100- to
999-unit quantities. The AMMP-6333 surface-mount device
pricing begins at $19.80 for the same quantities. The parts are
available now through distributors.
