Thus, the anti-parallel diodes more effectively block the small signals and prevent transmitter noise
from contaminating the receive signal.
For a GSM system, the allowed handset transmitter noise
, which can appear in the receive band of a co-located handset, is given in Table 1.
is often specified by its relative intensity noise, which also can be used to determine the noise figure of optical amplifiers.
The device also features a low-noise transmitter architecture, eliminating the need for transmit-path SAW filters, which are usually needed to prevent transmitter noise
from interfering with the receiver in full-duplex operation.
Looking into this test situation, four noise sources are found: the input thermal noise, receiver added thermal noise, transmitter noise
leakage in Rx band and quantization noise.
AIM InterMod 60 identifies external and internal interference including intermodulation, receiver desensitization, transmitter noise
, harmonics and spurious output in seconds.
This low attenuation causes considerable transmitter noise
interference in the receiver front end.
The high port-to-port isolation helps to protect sensitive receivers from transmitter noise
