(1) FCCSP LOP variant will have 0.5dB degradation in Noise figure and output power due to launcher integration.
(2) 1dB Compression Point (Out Of Band) is measured by feeding a continuous wave tone at 5% of the programmed HPF cut-off frequency (i.e. blocker tone). The compression point is determined by the blocker power that results in a 1dB compression of the blocker tone at the RX ADC.
(3) The analog IF stages include a second order high pass filter that can be configured to the following -6dB corner frequencies:
Available HPF Corner Frequencies (kHz) |
HPF |
300, 350, 700, 1400 |
The filtering performed by the digital baseband chain is targeted to provide:
- Less than ±0.5dB pass-band ripple/droop, and
- Better than 60dB anti-aliasing attenuation for any frequency that can alias back into the pass-band.
(4) Idle channel spur level is measured with a resolution BW of 100Hz
(5) The max ramp rate depends on the PLL bandwidth configuration set using the"AWR_APLL_SYNTH_BW_CONTROL_SB" API. For more details, refer to the mmWave Radar Interface Control document.
(6) VCO2 supports a maximum continuous range of 4.5GHz. The supported range can span 76-80.5GHz or 76.5-81GHz through VCO2_RANGE_CONFIG in AWR_ CAL_MON_FREQUENCY_* API.
Figure 7-1 shows variations of noise figure and in-band P1dB parameters with respect to receiver gain programmed plot.
