4.1.3. Reference Design

The RF interface has an impedance of 50

Ω

.

The reference design of RF antenna is shown as below. It

should reserve a

π

-type matching circuit for better RF performance. The capacitors are not mounted by

default.

Figure 31: Reference Circuit of Antenna Interface

4.2. Antenna Installation

4.2.1. Antenna Requirement

To minimize the loss on the RF trace and RF cable, they should be designed carefully. The following table
shows the requirement on GSM/UMTS antenna.

Table 26: Antenna Requirements

Type

Requirements

GSM850/EGSM900
UMTS 850/900

Cable insertion loss < 0.5dB

DCS1800/PCS1900
UMTS 1900/2100

Cable insertion loss < 0.9dB
