SDR Receiver HandHeld Radio Signal Analyzer Full Frequency DSP 4Layer PCB Components Thick

Feature: 1. Strictly abide by the design rules of high frequency electronic circuits in PCB design, realize digital and analog separate 2. With independent power layer, impedance matching in the circuit, after actual effect test, static background noise is extremely low, and can effectively shield itself from interference without sacrificing the sensitivity of the machine 3. Adopt ultra wide viewing angle IPS LCD capacitive touch screen, the viewing angle is not less than 155 degrees, the color is bright, the UI is clear, the side is not white and the screen is not dark 4. The sound cavity speaker with customized bass diaphragm is used inside the machine, with clear midrange, heavy bass and excellent sound quality 5. Adopt four layer PCB process, thicker, more stable structure, stronger performance Specification: Item Type: SDR Receiver Material: ABS Frequency Range: 200MHz, 400kHZ 2GHz Demodulation Mode: AM, SSB, WFM, CW Working Current: 300mA Sensitivity: 0.3u(at 200MHz) 3.5in SPI touch screen Dynamic Blocking Range: About 85dB Screen Display Bandwidth: 60kHz scalable Power Supply Mode: Built in battery power supply and USB power supply Motherboard: Four layer PCB process Antenna: SMA type antenna socket Screen Backlight: Controllable UHF band support Battery Model: Lithium battery(shipped with built in battery) Battery Capacity: 600mA.
