Radio Power
This chapter provides a detailed circuit description of the power distribution of an ASTRO XTS 5000
radio.
2.1
General
In the ASTRO XTS 5000 radio, power (B+) is distributed to two boards: the transceiver (RF) board
and the VOCON board (
for UHF Range 1 (R1) and 700–800 MHz, and
for VHF).
For kit NNTN5567, the VOCON board supplies VSW1, regulated
3.6Vdc, from the MAKO switching regulator to the XCVR.
In the case of a secure model radio, B+ is
also supplied to the encryption module.
Power for the radio is provided through a battery supplying a nominal 7.5 Vdc directly to the
transceiver. The following battery types and capacities are available:
