100W 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.
100W Rated RF Output
The unit provides 50dBm, equivalent to 100W, of rated RF output power and 47dBm of linear output power.
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 Control
The IP66 enclosure supports RS485/RS422 and Ethernet monitoring through SNMP and HTTP, with separate green normal-status and red fault-status indication.

FAQ
What is the 100W 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 50dBm, equivalent to 100W, 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?
The specified IF input-frequency range is 950–1950MHz.

B2B Procurement FAQ
What information should be included in an RFQ?
Please specify the required output-frequency band, quantity, AC supply conditions, monitoring interface and system-level connector requirements.

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 100W version?
Yes. The RFQ should state 50dBm rated output power, 47dBm linear output power and 860W power consumption to identify the required 100W configuration.
Which AC frequency should be used for procurement?
The formal specification states 50–60Hz, while a product photograph shows 47–63Hz. The required AC input-frequency range should be confirmed during quotation.
Can an evaluation unit be requested?
Evaluation-unit availability is not stated in the supplied documentation and must be confirmed during quotation.
Which specifications should be verified during incoming inspection?
Recommended checks include output-frequency version, input frequency, rated and linear output power, gain adjustment, VSWR, reference input, AC supply, RF interfaces and monitor-and-control communication.
Can protocol and interface documents be requested?
The applicable RS485, RS422, SNMP or HTTP documentation should be requested and confirmed before system integration.
Can packaging or identification labels be specified?
Packaging, product identification and labeling requirements are not stated in the supplied material and must be confirmed during quotation.
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.
