... TRANSMIT MODE Transmit mode is the normal active mode of the MT1530. The TXEN and SHDN pins must be held high in this mode. 8.1.2 TRANSMIT-DISABLE MODE Transmit-disable mode is typically used between bursts in TDMA systems. This mode shuts off the power amplifier while keeping the input amplifier and variable attenuator powered up ...

... TXEN input pin, but TXEN should be held low to minimize glitching when exiting this mode. 8.2 IC ARCHITECTURE The MT1530’s signal path consists of an input amplifier, a variable attenuator, and a power amplifier as shown in Figure 12. The input amplifier is a fixed-gain, low-noise, differential amplifier with a nominal input impedance of 1.85 kΩ. The variable attenuator is capable of a 51-dB attenuation range in 1-dB steps ...

... IC must already be powered up by having disabled shutdown mode. 8.3 SERIAL INTERFACE The serial interface (SI) programs the gain of the MT1530 using an 8-bit control word. The SI uses the gain control word to set the VA’s and PA’s gains individually using an internal decoder. It has an active-low chip-select ( synchronize to the incoming word ...
