1800-2200 MHz Advanced Doherty Alignment Module
MMDS20254H アラートの受信
The MMDS20254H is an advanced Doherty alignment module (ADAM), a new class of highly integrated GaAs MMIC control circuits designed specifically to optimize the performance of today's Doherty amplifiers.
ADAM provides the ability to align and optimize the RF performance in the carrier and peaking paths of a Doherty amplifier, thus providing improved overall BTS performance. When combined with Airfast® power transistors, this sophisticated technology provides increased manufacturing yields and power added efficiency. Available for frequency bands spanning 700 MHz to 2700 MHz.
Advantages:
Advantages:
- Production yield improvement and tighter parametric distributions
- Enables significant Doherty bandwidth improvement
- Optimized performance over the entire cellular frequency band
- Improved DPD correction with tighter performance distributions
- Increased system efficiency (across entire frequency band)
- Smaller output devices can be used, system efficiency is increased
- Enables consistent asymmetric Doherty with different transistors (works with symmetric Doherty as well)
- Field adjustment possible to optimize power amplifier performance under different conditions (power level, supply voltage, temperature)
