Jupiter 3-30
5.0 Electrical requirements
5.1 Power supply
5.1.1 Primary power
The Jupiter 3-30 receiver is designed to operate from a single supply voltage, meeting the requirements shown in
Table 5-1.
5.1.2 Battery backup (SRAM/RTC backup)
During ‘powered down’ conditions, the SRAM and RTC (Real Time Clock) may be kept operating by supplying
power from the VBATT as shown in Table 5-1.
5.1.3 VCC_RF power supply
The VCC_RF (pad 20) provides a regulated 2.85 V power source. The specifications for this supply are as follows:
5.1.4 External antenna voltage
DC power is supplied to the external antenna through the antenna power input pad (VANT). The receiver does not
use this supply. The DC supply to the RF connection does not use current limiting in the event of a short circuit.
Reference designs for antenna current limiting are available in the Jupiter 3-30 Integrator’s manual (LA000577).
The external antenna characteristics are as follows:

5.1.5 RF (Radio Frequency) input
RF input is 1575.42 MHz (L1 Band) at a level between –135 dBm and –159 dBm into a 50 ohm impedance. This input
may have a DC voltage impressed upon it to supply power to an active antenna. The maximum input return loss is
–9 dB.
