Radio devices and systems may include a pair of reflectors (e.g., parabolic reflectors) that are adjacent to each other and configured so that one of the reflectors is dedicated for sending/transmitting information, and the adjacent reflector is dedicated for receiving information. Both reflectors may be in a fixed configuration relative to each other so that they are aligned to send/receive in parallel. In many variations the two reflectors are formed of a single housing, so that the parallel alignment is fixed, and reflectors cannot lose alignment. The device/systems may be configured to allow switching between duplexing modes. These devices/systems may be configured as wide bandwidth zero intermediate frequency radios including alignment modules for automatic alignment of in-phase and quadrature components of transmitted signals. ## Claims ### Claim 1 A radio device for point-to-point transmission of high bandwidth signals, the device comprising: a housing unit forming a pair of reflectors including a first parabolic reflector and a second parabolic reflector forming, respectively, a first field and a second field, wherein the pair of reflectors are situated on a front side of the housing unit and aimed directionally parallel with each other such that the second parabolic reflector partially blocks the first field and diameter of the first parabolic reflector is less than diameter of the second parabolic reflector; and a printed circuit board (PCB) comprising at least a transmitter and a receiver, wherein the transmitter couples with the first reflector to form a dedicated transmitting antenna configured to transmit a signal but not to receive the signal and the receiver couples with the second reflector to form a dedicated receiving antenna configured to receive a signal but not to transmit the signal, such that the transmitter and the receiver are configured to switch between frequency division duplexing (FDD) and time division duplexing (TDD). ### Claim 2 (depends on 1) The device of claim 1, wherein the PCB is located in a cavity at a backside of the housing unit. ### Claim 3 (depends on 2) The device of claim 2, further comprising a backside cover that covers the cavity, thereby enclosing the PCB within the housing unit. ### Claim 4 (depends on 1) The device of claim 1, wherein the transmitter and the receiver are configured to dynamically switch between FDD and TDD when a received signal integrity falls below a threshold level. ### Claim 5 (depends on 1) The device of claim 1, wherein the transmitter and the receiver are configured to switch between FDD and TDD based on an error rate of the received signal. ### Claim 6 (depends on 1) The device of claim 1, wherein the transmitter and the receiver are configured to switch from FDD to TDD when an error rate of the received signal falls below a threshold level. ### Claim 7 (depends on 6) The device of claim 6, wherein the error rate corresponds to a packet error rate. ### Claim 8 (depends on 1) The device of claim 1, wherein the transmitter comprises a pair of transmitters and the receiver comprises a pair of receivers. ### Claim 9 (depends on 8) The device of claim 8, wherein the pair of transmitters are configured to concurrently transmit at orthogonal polarization with respect to each other. ### Claim 10 (depends on 1) The device of claim 1, wherein the transmitter and the receiver are configured to, respectively, transmit and receive at a same frequency channel. ### Claim 11 A radio device for point-to-point transmission of high bandwidth signals, the device comprising: a housing unit forming a pair of reflectors including a first parabolic reflector and a second parabolic reflector forming, respectively, a first field and a second field, wherein the pair of reflectors are situated on a front side of the antenna housing unit and aimed directionally parallel with each other such that the second parabolic reflector partially blocks the first field and diameter of the first parabolic reflector is less than diameter of the second parabolic reflector; and a printed circuit board (PCB) comprising at least a transmitter and a receiver, wherein the transmitter couples with the first reflector to form a dedicated transmitting antenna configured to transmit a signal but not to receive the signal and the receiver couples with the second reflector to form a dedicated receiving antenna configured to receive a signal but not to transmit the signal.
