PRODUCT OVERVIEW
Murata Power Solutions’ fully isolated Power
Amplifiers Quarter-Brick series of DC-DC convert-
ers is used in power radio-applications and is
optimized for the new generation of micro cell
transmitter applications requiring up to 150W. With
an input voltage range of 36 to 75 Volts, the PAQ
Series delivers up to 5 Amps of output current from
a fully regulated 29.8V output.
The PAQ offers a wide output voltage range
with the flexibility to adjust its output voltage with
the range of 23.84 to 32.78V (29.8V nom) that
accommodates multiple power-amplifiers designs,
industry leading efficiency (92.5% @29.8Vout full
load), and optimized design to reduce component
count for increased reliability. Design features
include an optional baseplate that is optimized for
RFPA applications being deployed in sealed box
applications with its heat sink fixed directly to the
host equipment chassis.
The PAQ is designed as an open-frame ¼ brick,
through-hole mounting, with options for positive
or negative logic and optional baseplate. Intended
markets include Micro Base Stations (Micro Cell
Transmitters, RFPA (radio frequency power amplifiers),
Microwave Radio communications, and Telecom and
Data Equipment applications where a 2:1 input volt-
age, 23 to 33Vout and isolated power is needed.
The PAQ offers Output over voltage, over current
protection, thermal shutdown, Input under-voltage
lockout, and short circuit protection. The option for
adding a baseplate for cold plate applications is
also available with an optional baseplate to ground
connect pin. The modules are designed to meet
Conducted EMI requirement for class B with an
optional external filter. The PAQ provides voltage
isolation (basic) from input to output of 2250V. The
PAQ series is certified to safety standards UL/EN/
IEC/CSA 60950-1, 2nd edition.
