RF Output Power
when set TX OFF < -40 dBm
CW/MOD Selection None
RF Band used and
RF equivalent
center frequency 70/80 GHz band (E-band)
in accordance with ETSI EN302 217-3 V1.3.1 (2009-07) Annex UC
70 GHz band: 71,125 to 75,625 MHz (f0 = 73,503 GHz)
80 GHz band: 81,125 to 85,625 MHz (f0 = 83,494 GHz)
Output Power
Density Mask In accordance with ETSI EN 302 217-3 V1.3.1 (2009-07) Annex-UC
measured at antenna port as shown in Figure 1.4-2a.
Emission Outside
the 71-76 GHz &
8.1-86 GHz Range (1) Output power spectral density, at antenna port, falling outside of
the 71-76 GHz band edge or below the lower band edge of 81-86
GHz band should be limited to a maximum of -55 dBW/MHz.
(2) For the band 86-92 GHz is allocated to Passive Services and, in
particular to Earth Extension Satellite Services, for their protection,
unwanted emission power density at the antenna port is in
accordance with Figure 1.4-2b.
TX Spurious
Emission - External
In accordance with ETSI EN301 390 V1.2.1 (2003-11)
For the interference into other systems operation for the fundamental
frequency range of 13 GHz to 150 GHz band, spurious emission
allowable is shown in Figure 1.4-2c.
(a) < -50 dBm in the frequency range of 30 MHz to 21.2 GHz
(b) < -30 dBm in the frequency range of 21.2 GHz to 2nd harmonic
Spurious emission is defined as any emission at frequencies which
are outside the nominal carrier frequency by more than +/- 250% of
the aggregated channel separation (4,500 MHz of 70/80 GHz band).
