20W Ka-Band SSPB
Technical Highlights
Four Ka-Band Frequency Options
The SSPB is available with four output-frequency ranges covering 27.50–31.00GHz. Each version converts a 950–1950MHz L-band input using its corresponding local oscillator frequency.
20W Rated RF Output
The 20W version provides 43dBm rated output power and 40dBm linear output power for Ka-band satellite uplink integration.
High Gain with Digital 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, with automatic switching between reference sources.
Outdoor System Integration
The IP66 enclosure supports operation from −40 to +60°C and provides serial or Ethernet monitoring through RS485/RS422, SNMP and HTTP.

Integration Notes
Select the required output-frequency version before ordering.
Use the matching WR-28 waveguide interface and verify system flange compatibility.
Confirm whether the standard 48V DC input or optional 24V DC input is required.
Provide adequate installation clearance for airflow around the cooling fins and fans.
Confirm the required RS485, RS422 or Ethernet monitoring method during system integration.
FAQ
What is the 20W 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 43dBm, approximately 20W, 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?
The specification identifies four output-band versions. The required frequency range should therefore be selected before ordering rather than interpreted as one continuously tunable 27.50–31.00GHz unit.
What is the input frequency?
The specified IF input frequency is 950–1950MHz.
What are the rated and linear output powers?
The 20W version provides 43dBm rated output power and 40dBm linear output power.
Can the gain be adjusted?
Yes. The unit provides 0–20dB of gain adjustment in 0.25dB steps, with a specified small-signal gain of 70dB.
Does the SSPB support an external reference?
Yes. It supports a 10MHz external reference at 0dBm ±5dB. The internal reference has stability of ≤±0.1ppm over temperature, and automatic reference switching is specified.
What RF interfaces are used?
The IF input uses an N-K 50Ω interface, the RF output uses a WR-28 grooved waveguide, and the coupled output uses a 2.92mm-K interface.
Which DC power inputs are supported?
The standard supply is +48V DC with a 36–75V operating range. A +24V DC version with a 20–32V range is optional.
What is the power consumption?
The specified power consumption for the 20W version is 160W at rated RF output power.
Which monitoring interfaces are available?
The specified monitor and control options include RS485/RS422 and Ethernet with SNMP and HTTP.
Is the SSPB suitable for outdoor installation?
The enclosure is rated IP66 and supports an operating temperature range of −40 to +60°C and 100% condensing humidity.
What are the dimensions and weight?
The outline dimensions are 165 × 105 × 77mm, and the specified weight is 2.0kg.
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 any 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 20W version?
Yes. The 20W configuration uses 43dBm rated output power, 40dBm linear output power and 160W power consumption. These values should be stated to avoid confusion with the higher-power values 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. The required supply version should be confirmed before ordering.
Can a sample unit be requested for system evaluation?
Sample availability should be confirmed with the supplier based on the required frequency band, power-supply version and monitoring configuration.
Which specifications should be verified during incoming inspection?
Recommended checks include output-frequency version, input frequency, rated and linear output power, gain adjustment, VSWR, interface type, power input and monitor-and-control communication.
Can protocol and interface information be requested?
Yes. Request the applicable RS485, RS422, SNMP or HTTP interface information for the selected unit before completing system integration.
Can packaging and product labels be specified for bulk orders?
Any packaging, identification or labeling requirements should be included in the RFQ for confirmation before an order is placed.
How are lead time, warranty and order terms confirmed?
Lead time, warranty coverage, commercial terms and shipping arrangements depend on the final configuration and order quantity and should be confirmed in the supplier quotation.
