AD831 provides +24 dBm third-order intercept , which can achieve -10 dBm LO consumption. It does not require high- LO drivers, and there is no corresponding shielding and isolation problems. Therefore, compared with passive mixers, it can System performance, reduce system cost. . 3. The mixer is designed to be powered by a single supply, and the RF, IF and LO ports have DC isolation capacitors for easy . The operating frequency of the RF and LO inputs can be as high as 500MHz. The IF output is a single-ended voltage output. It has an output bandwidth of 250 MHz. 4. A single resistor connected between pins OUT and FB is used to set the gain. The amplifier has low DC offset characteristics, so it can be used for DC coupling applications such as DC-baseband frequency conversion and quadrature amplitude demodulation 5.

is 1pcs 30A SimonK firmware Brushless ESC. Soldered with 3pcs 3.5mm gold female plug, very convenient to motor. Highest efficiency 100% N-FET design. Highest accuracy with Crystal Oscillator (Temperature won' affect the PWM operating range like other cheap ESC's). No low voltage cutoff, because any cutoff in a multirotor = crash. No over temp cutoff, because any cutoff in a multirotor = crash. Super high refresh rate, no buffering of the input signal, resulting in more than 490Hz response rate. 16KHz motor frequency, giving fastest response of the motor, and quietest operation as (no 8KHz squeal). Super simple, foolproof operation! Nothing to program other than the throttle range. ESC Specs: Cont. current: 30A Max. current: 35A Input Voltage: 2-4S / 4-12 cell Ni-/Ni-Cd BEC: 5V 2A (Linear mode Size: 55x26x8mm (length 145mm including cable) Weight: 22g Colour: Black material: plastic Package Contents: 1 x SIMONK 30A ESC Brushless Speed Controller Only the above package content, other products are not included.

Shop name:Chong Qing Shuo Yue Ke Ji You Xian Gong Si A Dummy Load is a device used to simulate an electrical load during testing. In an RF System a dummy load is used to simulate an antenna. By using a dummy load of an actual antenna, the transceiver can be tested and configured without radiating radio waves. The Dummy Load is in a way so it has a similar impedance to the real device will be connected to the RF System.Not using a dummy load and leaving the port open, can result in some unwanted reflections which can damage the RF System. Also, using a real antenna in the testing phase can result in some unwanted transmission in the lab which will interfere with other devices and technologies being tested. Warning: When the input is high than dummy , this is damage the dummy load Material:Plastic + Metal colour:black Package Contents: 1 x Dummy Load Only the above package content, other products are not included.
