2.2

RF Antenna Interface

The RF interface has an impedance of 50

Ω

. EMS31-V RF pads are located on pads 58, 59 and 

60 (pad 59 is RF_out pad, and pads 58 and 60 are GND pads). The antenna interface is typi-
cally connected by soldering it directly to the application’s PCB.

The antenna interface is designed to meet signal levels according to 3GPP specification. 
EMS31-V is capable of sustaining a 10:1 voltage standing wave ratio (VSWR) mismatch at the 
antenna line without any damage, even when transmitting at maximum RF power. Antenna pad 
is the antenna reference point (ARP) for EMS31-V. All RF data specified throughout this doc-
ument is related to ARP.

Note that DC blocking caps are needed in case DC is applied.

EMS31-V operates in the following frequency bands:
•

Band 4, AWS (1700/2100 MHz) (LTE HD-FDD)

•

Band 13, 700 MHz (LTE HD-FDD)

The following table provides basic information about RF parameters:
.

Please be aware that, in TS 36.521-1, Table 7.3.5-1, the power level is P

REFSENS

. This has a 

fixed relationship with the 

RS EPRE

 (reference signal energy per resource element), which is:

P

REFSENS

 = RS EPRE + 10 * log10(N_RE), 

where N_RE is the number of resource elements (12 *[number of RBs]).
