4. High Voltage Input: The amplifier board can operate with input voltages ranging from 24 to 26 volts, making it compatible with a wide range of power sources.
Cons of buying SRF286-75 75W Spectrian Linear RF Amplifier Board:1. Complex Design: The SRF286-75 is a more complex design compared to other RF amplifiers, and it may require specialized knowledge and equipment to properly design and implement a circuit using this amplifier.
2. Limited Frequency Bandwidth: While the SRF286-75 has a wide frequency range, its bandwidth is relatively limited, which may limit its use in some applications.
3. Cost: The SRF286-75 is a high-power amplifier, and as such, it may be more expensive than other RF amplifiers with lower power outputs.
Conclusion:The SRF286-75 75W Spectrian Linear RF Amplifier Board is a powerful and efficient amplifier that is suitable for high-power wireless communication systems. Its high power output, wide frequency range, and linear design make it an attractive option for many applications. However, its complex design and limited bandwidth may make it less suitable for some applications. Additionally, its higher cost compared to other RF amplifiers may be a consideration for some buyers. Ultimately, the decision to buy the SRF286-75 will depend on the specific requirements of the application and the budget of the buyer.
Recommendation:If you require a high-power RF amplifier with a wide frequency range and a linear design, the SRF286-75 may be a suitable option for you. However, it is important to carefully consider the complex design and limited bandwidth of the amplifier, as well as its higher cost, before making a decision. It is recommended to consult with an RF design engineer to determine if the SRF286-75 is the best fit for your specific application.

35 ghz 18DBG 24 26v this is a 75w linear amplifier board as removed from new Spectrian power which optimized for this board design rev a which has larger plated through holes and the have been sealed so silicon grease does not come top side when bolting down to heat-sink. 75w Spectrian linear rf amplifier board Weight is 6 ounces, drain current monitor for q1.
Power gain is 18db. 4dbm down looking at 2450 MHz you can see the output is 4db form 50 - 46dbm 40w are no connection.
Board needs to be mounted on heat-sink using silicon grease and 7ea.
Board dimensions are Input drive required for 75w output power is 1 volt out of drain current 6ghz with 50mhz division screws in existing holes.
Note the preamps I am driving this pa with is not linear frequency over full range as indicated by channel 1, temperature output 10mv degree.
The xrf286 lateral misfits used on this board can handle a 10:1 vst at full power so isolates are not required. Good quality SAM connectors are rated to 400w at 2ghz and work very well for this amp. The sweep photo shows one of these amps putting out 80w with about watt input at 2304ghz.
Were all number revs with open Visa. Saturated power is 80w. I also have some of the complete 180w Spectrian amplifiers available and will start a fixed price offer for you by request. Channel 2 is the input power with its reference set for 10w 40dbm 5dbm division.
6dbm, slightly over one watt. 1 volt out of drain current. Circuit board is on an integral. This is the final rev.
