The Supereta™ iQN Series offers an
industry standard quarter
brick
high current power module with true useable output power.
Its 92% typical
efficiency, a power density greater than 118W per
cubic inch, output voltage fold-
back current limit feature, and
s
uperior thermal performance make the iQN Series of power
modules ideally suited for wireless
applications to power various
RF amplifiers
. This rugged building block is designed to serve as
the core of the high reliability system. The droop current sharing
capability allows multiple modules connected in parallel to be
possible. A wide output voltage trim range, -40 to +10%,
sensing, and remote ON/OFF control are standard features
enhancing versatility.
