Description
PLO-5300 is a Phase Locked Oscillator
with internal fixed frequency divider of 520
and internal 10MHz TCXO. With external
reference applied, the unit will auto switch
and phase locked to generate output
frequency 520 times of input reference.

Operation Theory
PLO-5300 Phase Locked Oscillator is phase locked to its internal 10MHz Temperature
Compensated Crystal Oscillator (TCXO) when external reference signal is not applied.
With its internal fixed frequency divider ratio set to 520, the output frequency is default
at 10MHzx520 = 5200MHz. When external reference signal of 9.90MHz to 10.4MHz
with signal level above +3dBm applied to External Reference Input Port, the reference
signal will be detected and reference selection switch will be automatically switched to
its external reference source. The RF output frequency then will be 520 times of
external reference frequency which results in 5150MHz to 5400MHz range. Internal Low
Drop Out (LDO) linear voltage regulator allows unit to operate from 11V to 15V.

Battery
Small 5.2GHz CW Transmitter for Wireless LAN Propagation Study
With 12V battery and 5.2GHz antenna, PLO-5300 can be a simple CW transmitter with
+13dBm output for WLAN or 5.2GHz ISM band propagation study (does not require any
external reference input). With other external reference input between 9.9MHz to
10.4MHz, the output frequency can be tuned from 5150MHz to 5400MHz.

Receiver Frond-End
PLO-5300 can be used as tunable local oscillator in receiver front-end design. Its easy
to use and low cost helps system designer and integrator quick setup their bench test.
With +13dBm output power across the band, PLO-5300 is ideal for a Level 13 mixer
local oscillator source.
