Radio frequency performance
• Display average local noise: -158 dBm (normalized to 1 Hz)
Phase noise: -123 dBc/Hz at a 10 kHz offset, CF 640 MHz
Phase noise: -160 dBc/Hz at a 10 kHz offset, CF 640 MHz
• Third-order intermodulation cut-off point (TOI) : typical value +25 dBm
• Resolution bandwidth: 1 Hz to 50 MHz
• 1dB compression point: typical value +13dBm
The dynamic range of the adjacent channel leakage power (ACLR) in WCDMA is 77.5 dB. With noise correction enabled, it can reach 84 dB. Under 4-carrier conditions, the ACLR is 77dB (with noise correction).
