15.16 Antenna Interface

The balanced RF input and output of

CC1110 share two common pins and are

designed for a simple, low-cost matching

and balun network on the printed circuit

board. The receive and transmit switching

at the

CC1110 front-end is controlled by a

dedicated on-chip function, eliminating the

need for an external RX/TX-switch.

A few passive external components

combined

with

the

internal

RX/TX

switch/termination circuitry ensures match

in both RX and TX mode.

Although

CC1110 has a balanced RF

input/output, the chip can be connected to

a single-ended antenna with few external

low cost capacitors and inductors.

The passive matching/filtering network

connected to

CC1110 should have the

following differential impedance as seen

from the RF-port (RF_P and RF_N)

towards the antenna:

Zout 315MHz = 122 + j31 Ω

Zout 433MHz = 116 + j41 Ω

Zout 868MHz = 87 + j43 Ω

15.17 Radio Registers

This section describes all RF registers

used for control and status for the radio.

The RF registers reside in XDATA memory

space in the region 0xDF00-0xDF3D.

Table 51 gives an overview of register

addresses while the remaining tables in

this section describe each register.
