With IF input power ranges from −31 dBm to +4 dBm, the
HMC8200LP5ME provides 35 dB of digital gain control in 1 dB
steps and an analog voltage gain amplifier (VGA) continuously
controls the transmitter output power from −20 dBm to +5 dBm.
GENERAL DESCRIPTION
The HMC8200LP5ME is a highly integrated intermediate
frequency (IF) transmitter chip that converts the industry
standard 300 MHz to 400 MHz IF input signals to an 800 MHz to
4000 MHz single-ended radio frequency (RF) signal at its output.
The device also features three integrated power detectors. The
first detector (LOG_IF) can be utilized to monitor the IF input
power. The second detector (SLPD_OUT) is a square law power
detector that monitors the power entering the mixer. The third
power detector (LOG_RF) is used to monitor the output power,
which can be used for fine output power adjustment.
The IF transmitter chip is housed in a compact 5 mm × 5 mm
LFCSP package and supports complex modulations up to
1024 QAM. The HMC8200LP5ME simultaneously reduces the
design complexity of traditional microwave radios while realizing
significant size and cost improvements.
