Hardware update v2.1:

1. Upgrade and optimize circuit design, optimize wiring, and reduce phase noise.

2. Upgrade to a supercapacitor as a backup battery for GPS ephemeris data.

3. Upgraded to dual solid-state capacitor filtering, with a 1.5A three terminal voltage stabilization for a longer battery life, making the power supply more pure.

4. Upgrade to gold-plated SMA RF terminals.

Supports Beidou satellite and GPS satellite, dual output, each channel independently adjusts frequency, and each channel supports saving 10 sets of frequencies for arbitrary switching.

Parameters:

Power supply voltage: DC8-13V

Power consumption: ＜ 150mA

Frequency adjustment range: 10KHz-220MHz

Frequency accuracy: ± 0.1Hz

Output level: 12dBm ± 2dB (customizable from -10dBm to 10dBm with adjustable amplitude)

Frequency synthesizer crystal oscillator type: Temperature compensated crystal oscillator (tcxo)

Phase noise: -138dbc@10khz

Output type: Square wave

Harmonic suppression: Even harmonics are better than -50dBc, odd harmonics are better than -10dBc

Standard configuration: One host, one power supply, and one GPS antenna (with a feeder length of 3 meters)

Little knowledge: GPS tames frequency accuracy without considering the type of crystal oscillator used in the frequency synthesizer. After testing, even using a regular crystal oscillator can still correct the frequency error to 0.01Hz.
