BCM4319 Preliminary Data Sheet
WLAN RF Specifications
Section 11: WLAN RF Specifications
Introduction
The BCM4319 includes an integrated dual-band direct conversion radio that supports either the 2.4 GHz IEEE
802.11g band or the 5 GHz IEEE 802.11a band. The BCM4319 does not provide simultaneous 2.4 GHz and 5
GHz operation. This section describes the RF characteristics of the 2.4 GHz and 5 GHz sections of the radio.
Note: Unless otherwise stated, these specifications apply over the range of operating conditions
specified in Table 9, and Table 10 on page 57, and Table 11 on page 58. Outside these limits, functional
operation is not guaranteed.
Typical values apply for VBAT = 3.6V and ambient temperature = 25°C.
