American NuWaves company introduced NuPower NW-BSSPA-10W-1.0-2.5 Xtender type L and S dual-band power amplifier module, used for half-duplex RF transceiver with constant waveform envelope.
The power electronic device is based on a wide-band, high-efficiency NuPower type miniature power amplifier module. It can provide a minimum 10W RF peak power and 40dB gain in the frequency range of 1000MHz to 2500MHz and an average power conversion efficiency of 30%. The bidirectional power amplifier can also be used in adjacent bands, such as 900MHz commonly used in industry, scientific research and medical (ISM), but its peak power is lower. The device is compact and rugged, with a nickel-plated aluminum chassis size of 3 & TImes; 2 & TImes; 1.15inch, a device weight of less than 6oz (about 170g, translator's note), can be integrated into unmanned aircraft (UAV) and unmanned ground On small platforms such as vehicles (UGV). The device is also equipped with an automatic transmission detection circuit, which can achieve instantaneous switching of 1 microsecond between the transceiver modules, and its maximum noise figure is 3dB, which helps to improve the reception performance of the communication system.
4000 Puffs Disposable ecig have a completely enclosed design, reducing the need for charging and replacing cartridges. The no-charge design also reduces the occurrence of faults. It is understood that with rechargeable e-cigarettes, each cartridge needs to be charged at least once and the battery efficiency is extremely low, while the design of disposable ecig can solve this problem very well.
