What is HFDAG?
• High Frequency (HF) Distributed Amplifier Group (DAG) is the Navy’s
Program of Record (POR) HF system
• HFDAG is the follow-on replacement to HF Radio Group (HFRG)
• HFDAG is a modular architecture utilizing the following core
components:
¾ Digital Modular Radio (DMR) as the HF transceiver
¾ Commercial Off the Shelf (COTS) to the best extent possible
¾ Procurement for Navy-unique requirements
• Initial procurements are intended for Ship Construction (SCN) platforms::
¾ LPD (Amphibious Transport Dock), 16-Channel System
¾ DDG-51 (Guided Missile Destroyer), 8-Channel System
¾ DDG-1000 (Guided Missile Destroyer), 4-Channel System
¾ LHA (Amphibious Assault Ship), 16-Channel System
¾ CVN (Aircraft Carrier), 16-Channel System
• Space and Naval Warfare Command (SPAWAR) Systems Center
Pacific (SSC PAC) is the system designer and integrator
Interesting Fact: The USN has the highest HF performance demands and
channel count requirements of any Navy in the world

Digital Modular Radio Overview
• The DMR, AN/USC-61(C), is the first software defined radio to become
a communications system standard for the U.S. Armed Forces. The
compact, multi-channel DMR provides multiple waveforms and multilevel information security for voice and data communications from the
core of the network to the tactical edge
• Four full-duplex HF transceivers per radio
• Product Maturity: Full Rate Production (FRP)

HFDAG System
Pre/Post Selector (PPS)
• The PPS provides configurable attenuation, gain, limiting and bandpass
functions for each HF channel in the HFDAG system
¾ Protects Downstream equipment from high power interferers
¾ Provides filtering to achieve optimal frequency separation and maximize
simultaneous channel count operations
¾ Does not introduce any spurious emissions into the system
¾ Supports Half-Duplex Transmit and Receive
• The PPS is the Line Replaceable Unit (LRU)
¾ Four LRUs (4 Half-Duplex Channels) are installed in a single rack-width
• System Calibration (SYSCAL) using output power detector
¾ Link-11 requirement for power control of over/undershoot
10
HFDAG System
Flexible Power Management Unit (FPMU)
• Performs RF switching
between the DMR and PAs
¾ E.g., DMR 712 Channel 2 is
connected to PA #1
¾ May assign 1, 2 or 4 PAs per
DMR exciter
Simplified Single-Channel Block Diagram
11
HFDAG System
Power Amplifier Control Unit (PACU)
• PACU enables DMR HF
waveform control of up to eight
independent PAs
• The PACU stores health, status
and calibration information for
each PA
• The PACU is invisible to the
DMR radio
• Interfaces with the PPS, FPMU
and PA

HFDAG System
Receive Antenna Patch Panel (RAPP)
• RAPP provides manual connections for
up to 12 receivers
¾ LPD Baseline configuration has six output
ports per Antenna input port
¾ Other ships may use 12 ports per antenna
by using 2:1 splitter
¾ Each 16 channel system has two RAPPs
for up to 24 receive output ports
• Each RAPP unit provides spare ports, 2:1
splitter and cable connections for up to 4
receive antenna inputs
• Provides filtering and secondary surge
suppression

High Frequency Virtual Channel
Exploitation (HFVCE)
• DMR current scanning function allows users
to guard multiple channels/circuits
¾ Each DMR channel can guard up to 10
channels
¾ When a receive signal is detected the
scanning stops and the audio is passed to the
handset
¾ User picks up the handset and talks back on
the channel last received or selects one of
the other guarded channels/circuits
• HFVCE coming in DMR software version
6.5.1 allows four priority channels instead
of just one currently
¾ If no receive signal is detected, the user can
click the push-to-talk up to four times to
select one of the four priority channels. The
DMR will announce which channel the user
selected
¾ Allows single handset/RF channel to virtually
appear to the operator as up to four
independent RF channels
¾ Speed dialing
17
HFVCE is a Four-Fold
Capacity Increase
• Allows one DMR channel (with
one Red Phone) to effectively
guard four HF frequencies
• Each DMR channel can listen
to up to 10 channels.
¾ Upon receipt the operator can
talk to any of the incoming 10
stations via an operator
configurable dwell.
• Crypto keys need to be the
same on all channels.
18
High Frequency Dynamic
Routing (HFDR)
• HFDR coming in DMR software version 6.5.1 assigns
an HF frequency to up to eight audio ports
¾This effectively doubles the HF voice capability of a DMR
channel from four audio ports
¾Different crypto keys can be assigned to each audio port
¾The DMR does all the routing automatically
¾No action is required by the Red Phone user
¾Only four audio ports per channel have guaranteed service
and are priority based. Preemption is automatic for nonpriority users. Tones or audio is heard at the handset for
those non-priority users being kicked
19
High Frequency Dynamic
Routing (HFDR)
• Automatically selects an available RF transmission
path based upon pooled resource availability
¾Detects failures and selects alternate path
¾Distributes operational hours among assets, improving MTBF
¾Each circuit can be assigned a priority level

HFVCE and HFDR
• On a 16-channel HFDAG system
¾A mix of HF uses can be deployed on a single DMR; e.g. Ch 1
and 3 is DR, Ch 2 is Link-11 and Ch 4 is VCE
¾HFDR provides 32 HF frequencies
¾HFVCE provides 16 HF frequencies
¾Combined, they provide 40 frequencies
– 16 HFVCE on four DMR channels
– 24 HFDR on twelve DMR channels
