2. Detailed Interface Specifications
Note: If not specified, all electrical values are given for VBATT=3.7V and an operating temperature of
25°C.
For standard applications, VBATT and VBATT_PA must be tied externally to the same power
supply. For some specific applications, AirPrime HL7588 modules support separate VBATT and
VBATT_PA connection if requirements below are fulfilled.
2.1. Power Supply
The AirPrime HL7588 module is supplied through the VBATT signal with the following characteristics.

Note: Load capacitance for VBATT is around 32µF ± 20% embedded inside the module.
Load capacitance for VBATT_PA is around 10µF ± 20% embedded inside the module.
2.2. Current Consumption
The following table lists the current consumption of the AirPrime HL7588 at different conditions.
Note: Typical values are defined for VBATT/VBATT_PA at 3.7V and 25°C, for 50Ω impedance at all RF
ports. Maximum values are provided for VSWR4:1 with worst conditions among supported ranges
of voltages and temperature.
