SSG4522ATLX Smart PLL Frequency Synthesizer
Amplifier & configurable linear attenuator | 45 MHz – 22.6 GHz
Wideband synthesis. Configurable output attenuation.
Set the signal level your test needs
The SSG4522ATLX combines dual RF channel outputs, an amplified main output, and a configurable linear attenuator. Cover 45 MHz to 22.6 GHz with 0.1 Hz resolution and an attenuation range of 0 to 31.875 dB.
Start with the internal 100 MHz reference, or connect your preferred external 100 MHz reference. A single 5 V supply, iOS app, and serial UART interface support laboratory and field applications.

What's new compared with the SSG4522ALX?
Wider attenuation range
The on-board configurable linear attenuator provides 0–31.875 dB of attenuation in 0.125 dB steps, compared with the SSG4522ALX's 3–24 dB range.
Updated phase-noise specification
At 8 GHz with a 10 kHz offset, typical phase noise is specified at -108 dBc/Hz, compared with -105 dBc/Hz for the SSG4522ALX.
Output-power tradeoff
The attenuator introduces an average 2 dB insertion loss relative to the base SSG4522ALX. Output power varies with frequency; see the datasheet curves for your operating band.
Control & Integration
Use the Smart PLL iOS app or serial UART interface to control the synthesizer. SMA connections provide Lock Detect, Mute, and PSYNC functions for system integration.
Applications
- Reference clocks and local oscillators
- Radar, defense, and SATCOM
- Test and measurement
- Field signal generation
