1. A light detection and ranging (LIDAR) system comprising:
a light source configured to generate a transmit light beam;
a transceiver comprising:
a first local oscillator input configured to receive a first local oscillator signal;
a second local oscillator input configured to receive a second local oscillator signal;
a transmit input, positioned between the first local oscillator input and the second local oscillator input, configured to receive the transmit light beam, wherein the transmit input, the first local oscillator input, and the second local oscillator input are positioned on a first side of the transceiver;
a plurality of transmit outputs coupled to the transmit input, the plurality of transmit output respectively configured to transmit the transmit light beam into a surrounding environment; and
a plurality of receive inputs respectively configured to receive a return light beam from a surrounding environment; and
a detector configured to generate an electrical signal based on the return light beam and one or more local oscillator signals associated with the transmit light beam, the one or more local oscillator signals including the first local oscillator signal and the second local oscillator signal.
