Using the HMC602 as a detector in a RX AGC loop. The HMC602 is detecting the Tx signal (possibly radiated) at higher levels that the RX (conducted) signal. The RX path and AGC circuit is on the bottom side of the board and Tx is on the top side. Has anyone had similar issues with this device? Does anyone know how pins 21 and 22 are connected internally. The pins are called N/C, but datasheet says for the user to not connect these pins to anything externally.
