This fantastic strong signal handling is aided by the innovative configuration of a lateral DMOS FET QUAD first mixer running at 15V, relay switching in the front end (not diodes) and the use of shielded inductors throughout the signal path. Intermodulation free dynamic range with the 2.2kHz filter is typically 105dB at 100/200kHz spacing, 104dB at 20/40kHz and still better than 90dB at 5kHz. Where good strong signal handling, high performance and transportability are of great importance, the AR7030 is the solution offering an IP3 greater than +30dBm (typical +35dBm reduced by 10dB with the preamp on). The self tuning variable bandwidth synchronous detector is a pleasure to use and hangs on to the weakest of signals, audio quality is superb. Four 455 kHz IF filters are provided as standard with provision for a further two (including Collins mechanical filters), all of which are self-aligned by the receiver for optimum performance and passband symmetry this plus the standard fitted TCXO makes the AR7030 ideal for ECSS applications.
Frequency coverage is from 0 - 32 MHz all mode, AM, Synchronous AM, USB, LSB, CW, DATA and NFM. High performance coupled to enhanced microprocessor features and facilities forms the cornerstone of its success.
The AR7030 stunned the world when first released due to exceptionally high performance, indeed the AR7030 still wins the analogue-DSP battle in respect of high dynamic range and low noise, a testimony to the successful project between internationally acclaimed UK designer John Thorpe and AOR. Table-top Receiver of the Year award 1996/97 by the World Radio TV Handbook, it has also been awarded five stars by Passport to World Band Radio.
