TX500 ASK 1 GHz～100 MHz Transmitter Module

TX500 is an ASK wireless data transmitter module. It uses PLL frequency stabilization technology and is widely used in small area wireless data communications, such as wireless meter reading systems. The main technical features are as follows: ・The operating frequency is 100 MHz~1 GHz; ・The center frequency error is ±5×10-6 (TA=25℃); ・ASK modulation method; ・The modulation speed is DC~-100 kHz (50% duty cycle square wave, TTL signal); ・Point-to-point communication method, used in conjunction with RXl00 or RX500; ・The data interface is through a through-hole capacitor, the antenna interface uses Q9, and the input signal interface uses TTL/CMOS or RS-232; ・The maximum data rate is 100 Kb/s; ・The operating voltage is 12~15 V; ・The operating current is 170 mA (at 12 V), and the standby current is less than 10 uA; ・The radiated power (continuous wave) is 27 dB; ・ ・Transmission distance: In open areas, the antenna is 1.5 m above the ground, which is about 1.5 km; in open areas, the transmitting antenna is 30 m above the ground, which is about 2 km. In general urban environments, the antenna is 1.5 m above the ground, which is about 1 km. km, ・The operating temperature is -40～85℃(-10～60℃ is recommended).
