Noise figure of M20047/57 active GPS antenna
M20047-1 has SAW after LNA and M20057-1 has SAW before LNA. Why is the noise figure higher for M20047-1 (1.8dB) and lower for the M20057-1 (0.9dB). I would expect the reverse due to the first stage SAW losses for the M20057-1.

Hello Srossek,

Our apologies for the confusion. This is an error on our part in the data sheets, the figures should be the other way around. We’ll get the data sheets corrected and up-issued on our website.

Best regards,

Geoff S.
