looks interesting. Do you have a link or specs for it?
Found on eBay: SZM2166
SZM2166 RF Power Amplifier 2.4GHz 2W 33dBm 8-23V DC Wide Voltage Input for Signal Amplification
This is a 2W 2.4GHz RF power amplifier, and it can be considered as SZA2044 or RF2126. It comes with DC and supports wide voltage input (8-23V).
Supply voltage: 8-23V
Working frequency: 2450MHz
Input and output impedance: 50 ohms
Power: 2W (33dBm)
Interface: SMA outer screw inner hole
Antenna type: external
Size: 5 x 5 x 3cm
Application: for signal amplification
1 x RF Power Amplifier
PA Device is discontinued, but P1dB is listed as 35dBm by Qorvo which seems quite good.
Although this performance probably will be less on cheap FR4 PCB.
P1dB=35dBm at 6V
Three Stages of Gain: 37dB
802.11g 54Mb/s Class AB Performance
POUT=27dBm at 2.5%EVM, VCC
Active Bias with Adjustable Current
On-Chip Output Power Detector
Is this amplifier lineair?
if so, at what output power is this amplifier still linear.
I want to use this amp for DVB.
is there anyone who measured an amplifier with the SZM2166? The gain is lower than expected. The datasheet shows three stages compared to the SZA244.
I would like to see some S21-Measurement and if possible an intermodulation spectrum.
