Details: All RF Explorer models have some power ranges for input signal beyond which can be damaged. For most models, the limit is on +5dBm, some others are ok up to +10dBm but only WSUB3G (as well as the RF SMA connector on the right side in a 3G Combo) is protected up to +30dBm. Technical Data: Small and low weight custom aluminum case 3-in-1 device with Power Limiter, DC Block and Attenuator Easy to connect and disconnect when required Wide broadband frequency application Directional 1 Watt rating Suitable for all RF Explorer models, not required for WSUB3G. Frequency range: DC ~ 3.0 GHz DC block: +16V DC Input Power rating: 1 Watt (+30dBm) Output power max: +4 dBm. Attenuation: 6 dB Impedance (Nominal): 50Ω V.S.W.R (Max): 1.25 : 1 Connector type: SMA male – female Connector: Brass / Gold plating Body: Aluminum
