BCM4319 Preliminary Data Sheet
2.4 GHz Band Local Oscillator Specifications
b. Powers shown are at ChipOut. Measurements taken at the antenna port are lower due to insertion losses of the
external RF front end, including any RF switches or filters. Front end insertion losses are system-design
dependent.
The WLAN driver power-control algorithm keeps the output power within +/- 1.5 dB of the values specified in
NVRAM.
Output power can vary, depending on target output power and modulation offset settings in the NVRAM file.
Values shown assume the following NVRAM variable settings:
pa0maxpwr = 82
cckpo = 0
ofdmpo = 0x44442222
mcs2gpo0 = 0x8888
mcs2gpo1 = 0x8888
mcs2gpo4 = 0x8888
mcs2gpo5 = 0x8888
In this case an insertion loss of 1 dB is assumed between the output and the antenna port.
c. At 3 MHz offset from the carrier frequency.
