Features
• By using the keyed AGC system, which is effective in
improving the sensitivity suppression characteristic, in
combination with the antenna damping AGC (PIN diode
driver on chip) and MOS FET 2nd gate drive AGC, the
intermodulation characteristic for a large undesired signal
is greatly improved. It is also possible to use the keyed
AGC system in combination with the antenna damping
AGC or MOS FET 2nd gate drive AGC.
• The temperature characteristic and noise figure are
improved. The same supply voltage makes it easy to use
the LA1175, 1175M.
