Features
鈥?Improved interference characteristics
鈥?Expanded mixer input dynamic range
Mixer input usable sensitivity: 15 dB碌
Mixer input I.M. QS:
90 dB碌
(The dynamic range has been increased by 6 dB
over the earlier LA1175M.)
鈥?Development of a new wide-band AGC circuit
Improved interference characteristics for both near-
channel interference and far-channel interference
Improved interference characteristics for the TV band
鈥?Development of a 3D-AGC system
The adjacent channel two-signal interference
characteristics can be effectively improved without
degrading the strong-field three-signal interference
characteristics during keyed AGC operation.
鈥?Improved stability design
鈥?AGC circuit local oscillator isolation
Measures were taken to prevent the deterioration of
AMR, noise level, THD and other characteristics
during AGC operation.
鈥?AGC circuit incorrect operation measures
The LA1193M provides methods to prevent
incorrect operation due to local oscillator injection
and loss of DC balance.
