Reply To: SM200C noise at lower frequencies

[Justin Crooks]

You will notice in the specifications that the DANL (noise floor) specification is 4 dB higher below 700 MHz vs. above 700 MHz. A 4-5 dB step in the noise floor is normal. This is due to a design decision to optimize for noise figure in the 700 MHz – 2700 MHz communications band, and to push for better linearity at low frequencies.
