40W Ka-Band SSPB
Technical Highlights
Four Ka-Band Frequency Options
The SSPB is available in four output-frequency versions covering ranges from 27.50 to 31.00GHz. Each version converts a 950–1950MHz L-band input using its corresponding local oscillator frequency.
40W Rated RF Output
The 40W version provides 46dBm rated output power and 43dBm linear output power for Ka-band satellite uplink integration.
70dB Gain with Fine Adjustment
A small-signal gain of 70dB is combined with a 0–20dB adjustment range in precise 0.25dB steps.
Internal and External Reference Support
The unit supports a 10MHz external reference at 0dBm ±5dB and an internal reference with stability of ≤±0.1ppm over temperature. Automatic reference switching is specified.
Outdoor Monitoring and Integration
The IP66 enclosure supports operation from −40 to +60°C and provides serial or Ethernet monitoring through RS485/RS422, SNMP and HTTP.

FAQ
What is the 40W Ka-Band SSPB?
It is a solid-state power block upconverter that converts a 950–1950MHz L-band input into a Ka-band RF output while providing 46dBm, approximately 40W, of rated output power.
Which Ka-band output frequencies are available?
Four versions are specified: 27.50–28.50GHz, 28.25–29.25GHz, 29.00–30.00GHz and 30.00–31.00GHz.
Does one unit cover the complete 27.50–31.00GHz range?
No continuous full-band operation is specified. The documentation identifies four output-frequency versions, so the required range should be selected before ordering.
What is the input frequency?

B2B Procurement FAQ
What information should be included in an RFQ?
Please specify the required output-frequency band, quantity, standard 48V or optional 24V power input, monitoring interface and system-level connector requirements.
How should the output-frequency version be selected?
Select one of the four specified ranges according to the required satellite uplink frequency plan: 27.50–28.50GHz, 28.25–29.25GHz, 29.00–30.00GHz or 30.00–31.00GHz.
Should the RFQ identify this as the 40W version?
Yes. The 40W configuration uses 46dBm rated output power, 43dBm linear output power and 320W power consumption. These values should be stated to avoid confusion with the higher-power configurations shown on the combined specification sheet.
Is a 24V DC configuration available?
A +24V DC configuration with a 20–32V operating range is listed as optional. Its availability for the selected frequency version should be confirmed during quotation.
Can an evaluation unit be requested?
Evaluation-unit availability is not stated in the supplied material and must be confirmed during quotation for the required frequency, power-supply and monitoring configuration.
Which specifications should be verified during incoming inspection?
Recommended checks include the output-frequency version, input frequency, rated and linear output power, gain adjustment, VSWR, RF interfaces, power input and monitor-and-control communication.
Can protocol and interface documents be requested?
The applicable RS485, RS422, SNMP or HTTP interface documentation should be requested and confirmed for the selected unit before system integration.
Can packaging and product labels be specified for bulk orders?
Any packaging, identification or labeling requirements should be included in the RFQ and confirmed by the supplier before ordering.
How are MOQ, lead time, warranty and delivery terms confirmed?
These commercial terms are not provided in the supplied documentation and must be confirmed in the supplier quotation.
